7 FUNCTIONAL DESCRIPTION

7.1 FM I/Q-mixer

TheFMquadrature mixerconvertsFM RF (64 to 108 MHz

and 162.4 to 162.55 MHz) to an IF of 10.7 MHz.

It provides inherent image rejection and high dynamic

range. The image rejection can be switched from ‘low’

injection Local Oscillator (LO) to ‘high’ injection LO via the

I2C-bus. The mixer conversion gain can be increased by

6 dB via the I2C-bus. In this case the threshold of the FM

keyedAGChastobeloweredby6 dBtopreventthemixer

from being overloaded.

7.2 Buffer output for weather band ﬂag

Thebufferoutput(pinWBFLAG) is HIGH for weather band

mode.

7.3 VCO

The varactor tuned LC oscillator provides the local

oscillator signal for both FM and AM mixers. It has a

frequency range from 159.9 to 248.2 MHz.

7.4 Crystal oscillator

The crystal oscillator provides a 20.5 MHz signal that is

used for:

•Reference frequency for frequency synthesizer PLL

•Timing signal for the RDS update algorithm.

7.5 PLL

The fast synthesizer PLL tuning system with local control

is used for inaudible AF updating, combining fast PLL

jumps with low reference frequency breakthrough.

It is capable of tuning the following FM and AM bands:

•US FM and US IBOC DAB from 87.9 to 107.9 MHz

•US weather FM from 162.4 to 162.55 MHz

•Europe FM from 87.5 to 108 MHz

•Japan FM from 76 to 91 MHz

•East Europe FM from 64 to 74 MHz

•LW from 144 to 288 kHz

•MW from 522 to 1710 kHz (US AM band)

•SW from 5.73 to 9.99 MHz (including the 31 m, 41 m

and 49 m bands).

7.6 DAA

To reduce the number of manual alignments in production

the following I2C-bus controlled Digital Auto Alignment

(DAA) functions are included:

•FM RF DAA

– 7-bitDACto control the conversionoftheVCOtuning

voltage to FM antenna tank tuning voltage

– For cost reduction the diode at pin DAATD can be

omittedfromthisapplication.Inthiscase, pin DAATD

must be connected to ground, which reduces the

available alignment range (see Fig.7)

•Crystal frequency and general purpose DAA

– 5-bit DAC for adjustment of the crystal oscillator

frequency to align the actual IF frequency to the

centre frequency of IF selectivity inside the IF DSP. If

the IF DSP can be aligned to the actual IF frequency,

this DAA output can be used as general purpose

DAC. Figure 3 shows the application of the crystal

oscillator with frequency pulling.

7.7 FM keyed AGC

The AGC detects at the FM mixer input and the IF AGC

amplifier input. The AGC threshold for the FM mixer input

is programmable via the I2C-bus. When the threshold is

exceeded, the AGC sources a current to an external

PIN diode circuit, keeping the RF signal level at the FM

mixer input constant.

The keyed function shifts the threshold of the AGC if the

in-band signal is small. This reduces desensitization by

other strong transmitters. The amount of threshold shift is

limited to 10 dB. The keyed function can be activated via

the I2C-bus and is controlled by in-band level information

delivered from IF DSP via pin KAGC.

TheAGC canbeactivatedvia theI2C-busto sourceafixed

current as a local function for search tuning. In AM mode

the AGC can be activated to source a constant 10 mA

current into the FM PIN diode.

7.8 AM mixer

The AM mixer has a high dynamic range and converts

AM RF to an IF frequency of 10.7 MHz.

The outputs of the AM and FM mixers can be separated to

allow the use of different IF filters for AM and FM modes.

Figure 4 shows this optional application. By adding the

resistor R1 between pins AMIFIN and IFAGCBIAS the

input impedance of the IF AGC amplifier is matched to the

AM IF filter output impedance.

The input impedance of the AM IF filter is matched to

330 Ω with R2 and R3.

7.9 AM RFAGC

The AM wideband AGC in front of the AM mixer is realized

first by a cascoded NPN transistor, which controls the

transconductance of the RF amplifier JFET with 10 dB of

AGC range. Second, an AM PIN diode stage with 30 dB of

AGC range is available. The minimum JFET drain source

voltage is controlled by a DC feedback loop (pin

VAMCASFB) in order to limit the cascode AGC range to

10 dB. If the cascode AGC is not required, a simple

RF AGC loop is possible by using only a PIN diode.

In some conditions, noise behaviour will increase. In this

case pins VAMCAS and VAMCASFB have to be left

open-circuit. In FM mode, the cascode switches off the

JFET bias current to reduce total power consumption.

The AGC detection points for AM RF AGC are at the AM

mixer input (threshold programmable via the I2C-bus) and

the AM and FM IF AGC amplifier input (fixed threshold).

In FM mode the AM AGC can be activated via the I2C-bus

to sink a constant current of 1 mA from the PIN diode.

7.10 FM/AM RFAGC buffer

This output current can be used to reduce the gain of

active antennas before start of RF AGC.

The output (open-collector) sinks a current which in

AM mode is proportional to the voltage at pin TRFAMAGC

and in FM mode proportional to the RF level detector

voltage (pin TFMAGC) inside the FM AGC.

8 LIMITING VALUES

In accordance with the Absolute Maximum Rating System (IEC 60134).

Notes

1. To avoid damages and wrong operation it is necessary to keep all 8.5 V supply voltages at a higher level than any

5 V supply voltage. This is also necessary during power-on and power-down sequences. Precautions have to be

provided in such a way that interferences can not pull down the 8.5 V supply below the 5 V supply.

2. Machine model (R = 0 Ω, C = 200 pF).

3. Human body model (R = 1.5 kΩ, C = 100 pF).

AFHOLD signal is used to hold the quality information for signal processing of the main channel during the alternative frequency jumps. PLL registers

are loaded during load PLL = 1, but actual frequency jumps take place at the falling edge of this signal. IF counting is carried out during AFSAMPLE = 1.

10 µs after falling edge of AFSAMPLE result is valid for AF and remains valid until read by microcontroller. Quality tests in IF DSP should take place

during the HIGH phase of AFSAMPLE.

t1 is the internal TEF6721HL clock related logic delay: 100 µs.

t2 should be >1.1 ms to ensure correct loading of PLL for the main channel.

12 I2C-BUS PROTOCOL

12.1 I2C-bus speciﬁcation

SDA and SCL HIGH and LOW levels are specified

according to a 3.3 V I2C-bus. The bus pins tolerate also

thresholds of a 5 V bus.

The standard I2C-bus specification is expanded by the

following definitions.

IC addresses:

•1st IC address C2H: 1100001 R/W

•2nd IC address C0H: 1100000 R/W

•3rd IC address C4H: 1100010 R/W.

Structure of the I2C-bus logic: slave transceiver with auto

increment.

Subaddresses are not used.

The second I2C-bus address can be selected by

connecting pin ADDRSEL via a 120 kΩ resistor to GND.

The third I2C-bus address can be selected by connecting

pin ADDRSEL via a 33 kΩ resistor to GND.

The maximum bit rate for this device is 100 kbits/s.

TheI2C-businterface is extended withanenableinput(pin

BUSENABLE). If pin BUSENABLE is HIGH the

communication with the device is active; if pin

BUSENABLE is LOW the signals on the I2C-bus are

ignored so that higher bit rates (>100 kbits/s) can be used

to communicate with other devices on the same I2C-bus.

The enable signal must not change while bus

communication takes place.

No default settings at power-on reset. I2C-bus

transmission is required to program the IC.

12.1.1 DATA TRANSFER

Data sequence: address, byte 0, byte 1, byte 2, byte 3,

byte 4 and byte 5.

The data transfer has to be in this order. The LSB of the

address being logic 0 indicates a write operation.

Bit 7 of each byte is considered the MSB and has to be

transferred as the first bit of the byte.

The data becomes valid at the output of the internal

latches with the acknowledge of each byte. A STOP

condition after any byte can shorten transmission times.

When writing to the transceiver by using the STOP

condition before completion of the whole transfer:

•The remaining bytes will contain the old information

•If the transfer of a byte is not completed, this byte is lost

and the previous information is available.

12.1.2 FREQUENCY SETTING

For new frequency setting, in both AM and FM mode, the

programmable divider is enabled by setting bit PRESET to

logic 1. To select a frequency, two I2C-bus transmissions

are necessary:

•First: bit PRESET = 1

•Second: bit PRESET = 0.

12.2 I2C-bus protocol

16 SOLDERING

16.1 Introduction to soldering surface mount

packages

Thistext givesaverybrief insighttoa complextechnology.

A more in-depth account of soldering ICs can be found in

our

“Data Handbook IC26; Integrated Circuit Packages”

(document order number 9398 652 90011).

There is no soldering method that is ideal for all surface

mount IC packages. Wave soldering can still be used for

certainsurface mountICs,but itisnotsuitablefor finepitch

SMDs. In these situations reflow soldering is

recommended.

16.2 Reﬂow soldering

Reflow soldering requires solder paste (a suspension of

fine solder particles, flux and binding agent) to be applied

totheprinted-circuitboard by screen printing,stencillingor

pressure-syringe dispensing before package placement.

Driven by legislation and environmental forces the

worldwide use of lead-free solder pastes is increasing.

Several methods exist for reflowing; for example,

convection or convection/infrared heating in a conveyor

type oven. Throughput times (preheating, soldering and

cooling) vary between 100 and 200 seconds depending

on heating method.

Typical reflow peak temperatures range from

215 to 270 °C depending on solder paste material. The

top-surface temperature of the packages should

preferably be kept:

•below 220 °C (SnPb process) or below 245 °C (Pb-free

process)

– for all BGA and SSOP-T packages

– for packages with a thickness ≥2.5 mm

– for packages with a thickness < 2.5 mm and a

volume ≥350 mm3 so called thick/large packages.

•below 235 °C (SnPb process) or below 260 °C (Pb-free

process) for packages with a thickness < 2.5 mm and a

volume < 350 mm3 so called small/thin packages.

Moisture sensitivity precautions, as indicated on packing,

must be respected at all times.

16.3 Wave soldering

Conventional single wave soldering is not recommended

forsurface mountdevices(SMDs) orprinted-circuitboards

with a high component density, as solder bridging and

non-wetting can present major problems.

To overcome these problems the double-wave soldering

method was specifically developed.

If wave soldering is used the following conditions must be

observed for optimal results:

•Use a double-wave soldering method comprising a

turbulent wave with high upward pressure followed by a

smooth laminar wave.

•For packages with leads on two sides and a pitch (e):

– larger than or equal to 1.27 mm, the footprint

longitudinal axis is preferred to be parallel to the

transport direction of the printed-circuit board;

– smaller than 1.27 mm, the footprint longitudinal axis

must be parallel to the transport direction of the

printed-circuit board.

The footprint must incorporate solder thieves at the

downstream end.

•Forpackages withleadson foursides,thefootprintmust

be placed at a 45°angle to the transport direction of the

printed-circuit board. The footprint must incorporate

solder thieves downstream and at the side corners.

During placement and before soldering, the package must

be fixed with a droplet of adhesive. The adhesive can be

applied by screen printing, pin transfer or syringe

dispensing. The package can be soldered after the

adhesive is cured.

Typical dwell time of the leads in the wave ranges from

3 to 4 seconds at 250 °C or 265 °C, depending on solder

material applied, SnPb or Pb-free respectively.

A mildly-activated flux will eliminate the need for removal

of corrosive residues in most applications.

16.4 Manual soldering

Fix the component by first soldering two

diagonally-opposite end leads. Use a low voltage (24 V or

less) soldering iron applied to the flat part of the lead.

Contact time must be limited to 10 seconds at up to

300 °C.

When using a dedicated tool, all other leads can be

soldered in one operation within 2 to 5 seconds between

270 and 320 °C.

16.5 Suitability of surface mount IC packages for wave and reﬂow soldering methods

Notes

1. Formoredetailed information on theBGApackagesrefer to the

“(LF)BGAApplicationNote

”(AN01026);order a copy

from your Philips Semiconductors sales office.

2. All surface mount (SMD) packages are moisture sensitive. Depending upon the moisture content, the maximum

temperature (with respect to time) and body size of the package, there is a risk that internal or external package

cracks may occur due to vaporization of the moisture in them (the so called popcorn effect). For details, refer to the

Drypack information in the

“Data Handbook IC26; Integrated Circuit Packages; Section: Packing Methods”

3. These transparent plastic packages are extremely sensitive to reflow soldering conditions and must on no account

be processed through more than one soldering cycle or subjected to infrared reflow soldering with peak temperature

exceeding 217 °C±10 °C measured in the atmosphere of the reflow oven. The package body peak temperature

must be kept as low as possible.
