Agilent ADNB-6031 and ADNB-6032

Low Power Laser Mouse Bundles

Datasheet

Description

The Agilent ADNB-6031 and

ADNB-6032 low power laser

mouse bundles are the world’s

first laser-illuminated system

enabled for cordless

application. Powered by

Agilent LaserStream

technology, the mouse can

operate on many surfaces that

proved difficult for traditional

LED-based optical navigation.

Its high-performance, low

power architecture is capable

of sensing high-speed mouse

ADNB-6031 and ADNB-6032 Low Power Laser Mouse Bundles include:

motion while prolonging

battery life, two performance

areas essential in demanding

cordless applications.

The ADNS-6030 sensor along

with the ADNS-6120 or ADNS-

6130-001 lens, ADNS-6230-001

clip and ADNV-6330 VCSEL

form a complete and compact

laser mouse tracking system.

There are no moving part,

which means high reliability

and less maintenance for the

end user. In addition,

precision optical alignment is

not required, facilitating high

volume assembly.

This document will begin with

some general information and

usage guidelines on the bundle

set, followed by individual

detailed information on ADNS-

6030 laser mouse sensor,

ADNV-6330 VCSEL, ADNS-

6120 or ADNS-6130-001 lens

and ADNS-6230-001 clip.

Clip and ADNV-6330 VCSEL.

The components interlock as

they are mounted onto defined

features on the base plate.

The ADNS-6030 laser mouse

sensor is designed for

mounting on a through hole

PCB, looking down. There is

an aperture stop and features

on the package that align to

the lens.

The ADNV-6330 VCSEL is

recommended for illumination

provides a laser diode with a

single longitudinal and a single

transverse mode. It is

particularly suited as lower

power consumption and highly

coherent replacement of LEDs.

It also provides wider

operation range while still

remaining within single-mode,

reliable operating conditions.

The ADNS-6120 or ADNS-

6130-001 Laser Mouse Lens is

designed for use with ADNS-

6030 sensor and the

illumination subsystem

provided by the assembly clip

and the VCSEL. Together with

the VCSEL, the lens provides

the directed illumination and

optical imaging necessary for

proper operation of the Laser

Mouse Sensor. ADNS-6120 and

ADNS-6130-001 are precision

molded optical components

and should be handled with

care to avoid scratching of the

optical surfaces. ADNS-6120

also has a large round flange

to provide a long creepage

path for any ESD events that

occur at the opening of the

base plate.

The ADNS-6230-001 VCSEL

Assembly Clip is designed to

provide mechanical coupling of

the ADNV-6330 VCSEL to the

ADNS-6120 or ADNS-6130-001

lens. This coupling is essential

to achieve the proper

illumination alignment required

for the sensor to operate on a

wide variety of surfaces.

Agilent Technologies provides

an IGES file drawing

describing the base plate

molding features for lens and

PCB alignment.

Assembly Recommendation

1. Insert the sensor and all

other electrical components

into the application PCB

(main PCB board and

VCSEL PCB board).

2. Wave-solder the entire

assembly in a no-wash

solder process utilizing a

solder fixture. The solder

fixture is needed to protect

the sensor during the solder

process. It also sets the

correct sensor-to -PCB

distance, as the lead

shoulders do not normally

rest on the PCB surface.

The fixture should be

designed to expose the

sensor leads to solder while

shielding the optical

aperture from direct solder

contact.

3. Place the lens onto the base

plate.

4. Remove the protective

kapton tape from the optical

aperture of the sensor. Care

must be taken to keep

contaminants from entering

the aperture.

5. Insert the PCB assembly

over the lens onto the base

plate. The sensor aperture

ring should self-align to the

lens. The optical position

reference for the PCB is set

by the base plate and lens.

Note that the PCB motion

due to button presses must

be minimized to maintain

optical alignment.

Figure 3. Recommended PCB mechanical cutouts and spacing

6. Remove the protective cap

from the VCSEL.

7. Insert the VCSEL assembly

into the lens.

8. Slide the clip in place until

it latches. This locks the

VCSEL and lens together.

9. Tune the laser output power

from the VCSEL to meet the

Eye Safe Class I Standard

as detailed in the LASER

Power Adjustment

Procedure.

10. Install the mouse top case.

There must be a feature in

the top case (or other area)

to press down onto the

sensor to ensure the sensor

and lens are interlocked to

the correct vertical height.

Design considerations for improving

ESD Performance

For improved electrostatic

discharge performance, typical

creepage and clearance

distance are shown in the

table below. Assumption: base

plate construction as per the

Agilent supplied IGES file and

ADNS-6130-001 trim lens (or

ADNS-6120 round lens).

Typical Distance Millimeters

Creepage 12.0

Clearance 2.1

Note that the lens material is

polycarbonate and therefore,

cyanoacrylate based adhesives

or other adhesives that may

damage the lens should NOT

be used.

LASER Drive Mode

The laser is driven in pulsed

mode during normal operation.

A calibration mode is provided

which drives the laser in

continuous (CW) operation.

Eye Safety

The ADNS-6030 and the

associated components in the

schematic of Figure 5 are

intended to comply with Class

1 Eye Safety Requirements of

IEC 60825-1. Agilent

Technologies suggests that

manufacturers perform testing

to verify eye safety on each

mouse. It is also recommended

to review possible single fault

mechanisms beyond those

described below in the section

“Single Fault Detection”. Under

normal conditions, the ADNS-

6030 generates the drive

current for the laser diode

(ADNV-6330).

In order to stay below the

Class 1 power requirements,

LASER_CTRL0 (register 0x1a),

LASER_CTRL1 (register 0x1f),

LSRPWR_CFG0 (register 0x1c)

and LSRPWR_CFG1 (register

0x1d) must be programmed to

appropriate values. The system

comprised of the ADNS-6030

and ADNV-6330, is designed to

maintain the output beam

power within Class 1

requirements over components

manufacturing tolerances and

the recommended temperature

range when adjusted per the

procedure below and

implemented as shown in the

recommended application

circuit of Figure 5. For more

information, please refer to

Agilent ADNB-6031 and

ADNB-6032 Laser Mouse

Sensor Eye Safety Application

Note AN 5230.

LASER Power Adjustment Procedure

1. The ambient temperature

should be 25C +/- 5C.

2. Set VDD to its permanent

value.

3. Set the Range bit (bit 7 of

4. Set the Range_C complement

bit (bit 7 of register 0x1f) to

5. Set the Match_bit (bit 5 of

value for the bin designation

of the laser being used.

6. Set the Match_C_bit (bit 5

of register 0x1f) to the

complement of the

Match_bit.

7. Enable the Calibration mode

by writing to bits [3,2,1] of

will be driven with 100%

duty cycle.

8. Write the Calibration mode

complement bits to register

0x1f.

9. Set the laser current to the

minimum value by writing

0x00 to register 0x1c, and

the complementary value

0xFF to register 0x1d.

10. Program registers 0x1c and

0x1d with increasing values

to achieve an output power

as close to 506uW as

possible without exceeding

it. If this power is obtained,

the calibration is complete,

skip to step 14.

11. If it was not possible to

achieve the power target, set

the laser current to the

minimum value by writing

0x00 to register 0x1c, and

the complementary value

0xff to register 0x1d.

12. Set the Range and Range_C

bits in registers 0x1a and

0x1f, respectively, to choose

to the higher laser current

range.

13. Program registers 0x1c and

0x1d with increasing values

to achieve an output power

as close to 506uW as

possible without exceeding

it.

14. Save the value of registers

0x1a, 0x1c, 0x1d, and 0x1f

in non-volatile memory in

the mouse. These registers

must be restored to these

values every time the

ADNS-6030 is reset.

15. Reset the mouse, reload

the register values from

non-volatile memory, enable

Calibration mode, and

measure the laser power to

verify that the calibration is

correct.

Good engineering practices

such as regular power meter

calibration, random quality

assurance retest of calibrated

mice, etc. should be used to

guarantee performance,

reliability and safety for the

product design.

LASER Output Power

The laser beam output power

as measured at the navigation

surface plane is specified

below. The following conditions

apply:

1. The system is adjusted

according to the above

procedure.

2. The system is operated

within the recommended

operating temperature range.

3. The VDD value is no greater

than 300mV above its value

at the time of adjustment.

4. No allowance for optical

power meter accuracy is

assumed.

Disabling the LASER

LASER_NEN is connected to

the gate of a P-channel

MOSFET transistor which when

ON connects VDD to the

LASER. In normal operation,

LASER_NEN is low. In the

case of a fault condition

(ground or VDD at XY_LASER),

LASER_NEN goes high to turn

the transistor off and

disconnect VDD from the

LASER.

Single Fault Detection

ADNS-6030 is able to detect a

short circuit or fault condition

at the XY_LASER pin, which

could lead to excessive laser

power output. A path to

ground on this pin will trigger

the fault detection circuit,

which will turn off the laser

drive current source and set

the LASER_NEN output high.

When used in combination

with external components as

shown in the block diagram

below, the system will prevent

excess laser power for a

resistive path to ground at

XY_LASER by shutting off the

laser. In addition to the

ground path fault detection

described above, the fault

detection circuit is

continuously checked for

proper operation by internally

generating a path to ground

with the laser turned off via

LASER_NEN. If the XY_LASER

pin is shorted to VDD, this test

will fail and will be reported

as a fault.

Agilent ADNS-6030

Laser Mouse Sensor

Theory of Operation

The ADNS-6030 is based on

LaserStream Technology,

which measures changes in

position by optically acquiring

sequential surface images

(frames) and mathematically

determining the direction and

magnitude of movement.

The ADNS-6030 contains an

Image Acquisition System

(IAS), a Digital Signal

Processor (DSP), and a four

wire serial port. The IAS

acquires microscopic surface

images via the lens and

illumination system. These

images are processed by the

DSP to determine the direction

Chip Select Operation

The serial port is activated

after NCS goes low. If NCS is

raised during a transaction,

the entire transaction is

aborted and the serial port

will be reset. This is true for

all transactions. After a

transaction is aborted, the

normal address-to-data or

transaction-to-transaction

delay is still required before

beginning the next transaction.

To improve communication

reliability, all serial

transactions should be framed

by NCS. In other words, the

port should not remain

enabled during periods of non-

use because ESD and EFT/B

events could be interpreted as

serial communication and put

the chip into an unknown

state. In addition, NCS must

be raised after each burst-

mode transaction is complete

to terminate burst-mode. The

port is not available for

further use until burst-mode is

terminated.

Synchronous Serial Port

The synchronous serial port is

used to set and read

parameters in the ADNS-6030,

and to read out the motion

information.

The port is a four-wire port.

The host micro-controller

always initiates communication;

the ADNS-6030 never initiates

data transfers. SCLK, MOSI,

and NCS may be driven

directly by a micro-controller.

The port pins may be shared

with other SPI slave devices.

When the NCS pin is high, the

inputs are ignored and the

output is tri-stated.

The lines that comprise the

SPI port:

SCLK: Clock input. It is

always generated by the

master (the micro-controller).

MOSI: Input data. (Master

Out/Slave In)

MISO: Output data. (Master

In/Slave Out)

NCS: Chip select input

(active low). NCS needs to be

low to activate the serial port;

otherwise, MISO will be high Z,

and MOSI & SCLK will be

ignored. NCS can also be

used to reset the serial port in

case of an error.

Motion Pin Timing

The motion pin is a level-

sensitive output that signals the

micro-controller when motion

has occurred. The motion pin

is lowered whenever the

motion bit is set; in other

words, whenever there is data

in the Delta_X or Delta_Y

registers. Clearing the motion

bit (by reading Delta_X and

Delta_Y, or writing to the

Motion register) will put the

motion pin high.

LASER Mode

For power savings, the VCSEL

will not be continuously on.

ADNS-6030 will flash the

VCSEL only when needed.

Read Operation

A read operation, defined as

data going from the ADNS-

6030 to the micro-controller, is

always initiated by the micro-

controller and consists of two

bytes. The first byte contains

the address, is sent by the

micro-controller over MOSI,

and has a “0” as its MSB to

indicate data direction. The

second byte contains the data

and is driven by the ADNS-

6030 over MISO. The sensor

outputs MISO bits on falling

edges of SCLK and samples

MOSI bits on every rising edge

of SCLK.

Write Operation

Write operation, defined as

data going from the micro-

controller to the ADNS-6030,

is always initiated by the

micro-controller and consists

of two bytes. The first byte

contains the address (seven

bits) and has a “1” as its MSB

to indicate data direction. The

second byte contains the data.

The ADNS-6030 reads MOSI on

rising edges of SCLK.

Figure 14. MISO Delay and Hold Time

Note: The 0.5/fSCLK minimums

high state of SCLK is also the

minimum MISO data hold time

of the ADNS-6030. Since the

falling edge of SCLK is actually

the start of the next read or

write command, the ADNS-

6030 will hold the state of

data on MISO until the falling

edge of SCLK.

Required timing between Read and

Write Commands

There are minimum timing

requirements between read

and write commands on the

serial port.

If the rising edge of the SCLK

for the last data bit of the

second write command occurs

before the required delay

(tSWW), then the first write

command may not complete

correctly.

If the rising edge of SCLK for

the last address bit of the read

command occurs before the

required delay (tSWR), the

write command may not

complete correctly.

During a read operation SCLK

should be delayed at least

tSRAD after the last address

data bit to ensure that the

ADNS-6030 has time to

prepare the requested data.

The falling edge of SCLK for

the first address bit of either

the read or write command

must be at least tSRR or tSRW

after the last SCLK rising edge

of the last data bit of the

previous read operation.

Burst Mode Operation

Burst mode is a special serial

port operation mode that may

be used to reduce the serial

transaction time for a motion

read. The speed improvement

is achieved by continuous data

clocking to or from multiple

registers without the need to

specify the register address,

and by not requiring the

normal delay period between

data bytes.

Burst mode is activated by

reading the Motion_Burst

respond with the contents of

the Motion, Delta_X, Delta_Y,

SQUAL, Shutter_Upper,

Shutter_Lower and

Maximum_Pixel registers in

that order. The burst

transaction can be terminated

anywhere in the sequence after

the Delta_X value by bringing

the NCS pin high. After

sending the register address,

the micro-controller must wait

tSRAD and then begin reading

data. All data bits can be

read with no delay between

bytes by driving SCLK at the

normal rate. The data are

latched into the output buffer

after the last address bit is

received. After the burst

transmission is complete, the

micro-controller must raise the

NCS line for at least tBEXIT to

terminate burst mode. The

serial port is not available for

use until it is reset with NCS,

even for a second burst

transmission.

Notes on Shutdown and Forced Rest

The ADNS-6030 can be set in

Rest mode through the

Configuration_Bits register

(0x11). This is to allow for

further power savings in

applications where the sensor

does not need to operate all

the time.

The ADNS-6030 can be set in

Shutdown mode by writing

0xe7 to register 0x3b. The SPI

port should not be accessed

when Shutdown mode is

asserted, except the power-up

command (writing 0x5a to

the same SPI bus can be

accessed, as long as the

sensor’s NCS pin is not

asserted.) The table below

shows the state of various pins

during shutdown. To deassert

Shutdown mode:

1. Write 0x5a to register 0x3a

2. Wait for tWAKEUP

3. Write 0xFE to register 0x28

4. Any register settings must

then be reloaded.

*1 NCS pin must be held to 1

(high) if SPI bus is shared

with other devices. It is

recommended to hold to 1

(high) during Power Down

unless powering up the

Sensor. It must be held to 0

(low) if the sensor is to be

re-powered up from

shutdown (writing 0x5a to

Note: There are long wakeup

times from shutdown and

forced Rest. These features

should not be used for power

management during normal

mouse motion.

Notes on Power-up

The ADNS-6030 does not

perform an internal power up

self-reset; the

POWER_UP_RESET register

must be written every time

power is applied. The

appropriate sequence is as

follows:

1. Apply power

2. Drive NCS high, then low to

reset the SPI port

3. Write 0x5a to register 0x3a

4. Wait for tWAKEUP

5. Write 0xFE to register 0x28

6. Read from registers 0x02,

0x03 and 0x04 (or read

these same 3 bytes from

burst motion register 0x42)

one time regardless of the

motion pin state.

During power-up there will be

a period of time after the

power supply is high but

before any clocks are available.

The table below shows the

state of the various pins

during power-up and reset.

Field MOT PIXRDY PIXFIRST OVF LP_VALID FAULT Reserved Reserved

Data Type : Bit field.

USAGE : Register 0x02 allows the user to determine if motion has occurred since the last time it

was read. If the MOT bit is set, then the user should read registers 0x03 and 0x04 to get the

accumulated motion. Read this register before reading the Delta_X and Delta_Y registers.

Writing anything to this register clears the MOT and OVF bits, Delta_X and Delta_Y registers. The

written data byte is not saved.

Internal buffers can accumulate more than eight bits of motion for X or Y. If either one of the

internal buffers overflows, then absolute path data is lost and the OVF bit is set. To clear

theoverflow, write anything to this register.

Check the OVR bit if more than 4" of motion is accumulated without reading it. If bit set, discard

the motion as erroneous. Write anything to this register to clear the overflow condition.

The PIXRDY bit will be set whenever a valid pixel data byte is available in the Pixel_Dump

pointer has beenreset to pixel 0,0 on the initial write to Pixel_Grab, check to see if PIXFIRST is

set to high.

NOTE: Agilent recommends that registers 0x02, 0x03 and 0x04 be read sequentially.

Data Type : Upper 8 bits of a 9-bit unsigned integer.

USAGE : SQUAL (Surface Quality) is a measure of the number of valid features visible by the

sensor in the current frame.

The maximum SQUAL register value is 127. Since small changes in the current frame can result

in changes in SQUAL, variations in SQUAL when looking at a surface are expected. The

graph below shows 800 sequentially acquired SQUAL values, while a sensor was moved slowly

over white paper. SQUAL is nearly equal to zero, if there is no surface below the sensor.

SQUAL is typically maximized when the navigation surface is at the optimum distance from the

imaging lens (the nominal Z-height).

USAGE : For test purposes, the sensor will read out the contents of the pixel array, one pixel per

frame. To start a pixel grab, write anything to this register to reset the pointer to pixel 0,0.

Then read the PIXRDY bit in the Motion register. When the PIXRDY bit is set, there is valid data

in this register to read out. After the data in this register is read, the pointer will automatically

increment to the next pixel. Reading may continue indefinitely; once a complete frame’s worth of

pixels has been read, PIXFIRST will be set to high to indicate the start of the first pixel and the

address pointer will start at the beginning location again.

Single-Mode Vertical-Cavity Surface Emitting Laser

(VCSEL)

Figure 27. Outline Drawing for ADNV-6330 VCSEL

W = Bin#

X = Bin Letter

Y = Subcon Code

Z = Die Source

Description

This advanced class of VCSELs

was engineered by Agilent to

provide a laser diode with a

single longitudinal and a single

transverse mode. In contrast to

most oxide-based single-mode

VCSELs, this class of Agilent

VCSELs remains within single

mode operation over a wide

range of output power. The

ADNV-6330 has significantly

lower power consumption than

a LED. It is an excellent

choice for optical navigation

applications.

Features

· Advanced Technology VCSEL chip

· Single Mode Lasing operation

· Non-hermetic plastic package

· 832-865 nm wavelength

Notes:

Because the can is not sealed,

the protective kapton tape

should not be removed until

just prior to assembly into the

ADNS-6120 or ADNS-6130-001

lens.

Absolute Maximum Ratings:

Comments:

VCSELs are sorted into bins as

specified in the power

adjustment procedure section

in the ADNS-6030 laser sensor

datasheet. Appropriate binning

resistor and register data

values are used in the

application circuit to achieve

the target output power.

Optical/Electrical Characteristics (at Tc = 5°C to 45°C):

Comments:

1. Stresses greater than those

listed under “Absolute

Maximum Ratings” may

cause permanent damage to

the device. These are the

stress ratings only and

functional operation of the

device at these or any other

condition beyond those

indicated for extended

period of time may affect

device reliability.

2. The maximum ratings do

not reflect eye-safe

operation. Eye safe

operating conditions are

listed in the power

adjustment procedure

section in the ADNS-6030

laser sensor datasheet.

3. The inherent design of this

component causes it to be

sensitive to electrostatic

discharge. The ESD

threshold is listed above. To

prevent ESD-induced

damage, take adequate ESD

precautions when handling

this product.

Notes:

1. Duration = 100ms, 10% duty cycle

2. I = 10µA

3. See IR reflow profile (Figure 36)

Notes:

1. Maximum output power under any condition. This is not a recommended operating condition and does not meet eye safety requirements.

2. At 500uW output power.

Danger:

When driven with current or

temperature range greater than

specified in the power

adjustment procedure section,

eye safety limits may be

exceeded. The VCSEL should

then be treated as a Class IIIb

laser and as a potential eye

hazard.
