MT9V032: 1/3-Inch Wide-VGA Digital Image Sensor
General Description
Preliminary
General Description
The Micron Imaging MT9V032 is a 1/3-inch wide-VGA format CMOS active-pixel digital
image sensor with global shutter and high dynamic range (HDR) operation. The sensor
has specifically been designed to support the demanding interior and exterior unat-
tended surveillance imaging needs, which makes this part ideal for a wide variety of
imaging applications in real-world environments.
This wide-VGA CMOS image sensor features DigitalClarityMicrons breakthrough
low-noise CMOS imaging technology that achieves CCD image quality (based on signal-
to-noise ratio and low-light sensitivity) while maintaining the inherent size, cost, and
integration advantages of CMOS.
The active imaging pixel array is 752H x 480V. It incorporates sophisticated camera
functions on-chip—such as binning 2 x 2 and 4 x 4, to improve sensitivity when oper-
ating in smaller resolutions—as well as windowing, column and row mirroring. It is
programmable through a simple two-wire serial interface.
The MT9V032 can be operated in its default mode or be programmed for frame size,
exposure, gain setting, and other parameters. The default mode outputs a wide-VGA-
size image at 60 frames per second (fps).
An on-chip analog-to-digital converter (ADC) provides 10 bits per pixel. A 12-bit resolu-
tion companded for 10-bits for small signals can be alternatively enabled, allowing more
accurate digitization for darker areas in the image.
In addition to a traditional, parallel logic output the MT9V032 also features a serial low-
voltage differential signaling (LVDS) output. The sensor can be operated in a stereo-
camera mode, and the sensor, designated as a stereo-master, is able to merge the data
from itself and the stereo-slave sensor into one serial LVDS stream.

Appendix A Serial Configurations
Preliminary
Appendix A Serial Configurations
With the LVDS serial video output, the deserializer can be up to 8 meters from the
sensor. The serial link can save on the cabling cost of 14 wires (DOUT[9:0], LINE_VALID,
FRAME_VALID, PIXCLK, GND). Instead, just three wires (two serial LVDS, one GND) are
sufficient to carry the video signal.
Configuration of Sensor for Stand-Alone Serial Output with Internal PLL
In this configuration, the internal PLL generates the shift-clk (x12). The LVDS pins
SER_DATAOUT_P and SER_DATAOUT_N must be connected to a deserializer (clocked
at approximately the same system clock frequency).
Figure 6 shows how a standard off-the-shelf deserializer (National Semiconductor
DS92LV1212A) can be used to retrieve the standard parallel video signals of DOUT[9:0],
LINE_VALID and FRAME_VALID.
Figure 6: Stand-Alone Topology
Typical configuration of the sensor:
1. Power up sensor.
2. Enable LVDS driver (set R0xB3[4]= 0).
3. De-assert LVDS power-down (set R0xB1[1] = 0.
4. Issue a soft reset (set R0x0C[0] = 1 followed by R0x0C[0] = 0.
If necessary:
5. Force sync patterns for the deserializer to lock (set R0xB5[0] = 1).
6. Stop applying sync patterns (set R0xB5[0] = 0).

Appendix A Serial Configurations
Preliminary
Configuration of Sensor for Stereoscopic Serial Output with Internal PLL
In this configuration the internal PLL generates the shift-clk (x18) in phase with the
system-clock. The LVDS pins SER_DATAOUT_P and SER_DATAOUT_N must be
connected to a deserializer (clocked at approximately the same system clock frequency).
Figure 7 shows how a standard off-the-shelf deserializer can be used to retrieve back
DOUT(9:2) for both the master and slave sensors. Additional logic is required to extract
out LINE_VALID and FRAME_VALID embedded within the pixel data stream.
Figure 7: Stereoscopic Topology
Typical configuration of the master and slave sensors:
1. Power up the sensors.
2. Broadcast WRITE to de-assert LVDS power-down (set R0xB1[1] = 0).
3. Individual WRITE to master sensor putting its internal PLL into bypass mode (set
R0xB1[0] = 1).
4. Broadcast WRITE to both sensors to set the stereoscopy bit (set R0x07[5] = 1).
5. Make sure all resolution, vertical blanking, horizontal blanking, window size, and
AEC/AGC configurations are done through broadcast WRITE to maintain lockstep.
6. Broadcast WRITE to enable LVDS driver (set R0xB3[4] = 0).
7. Broadcast WRITE to enable LVDS receiver (set R0xB2[4] = 0).
8. Individual WRITE to master sensor, putting its internal PLL into bypass mode (set
R0xB1[0] = 1).
9. Individual WRITE to slave sensor, enabling its internal PLL (set R0xB1[0] = 0).
10. Individual WRITE to slave sensor, setting it as a stereo slave (set R0x07[6] = 1).
11. Individual WRITEs to master sensor to minimize the inter-sensor skew (set
R0xB2[2:0], R0xB3[2:0], and R0xB4[1:0] appropriately). Use R0xB7 and R0xB8 to get
lockstep feedback from stereo_error_flag.
12. Broadcast WRITE to issue a soft reset (set R0x0C[0] = 1 followed by R0x0C[0] = 0).
Note: The stereo_error_flag is set if a mismatch has occurred at a reserved byte (slave and
master sensor’s codes at this reserved byte must match). If the flag is set, steps 11 and
12 are repeated until the stereo_error_flag remains cleared.

Appendix A Serial Configurations
Preliminary
Broadcast and Individual Writes for Stereoscopic Topology
In stereoscopic mode, the two sensors are required to run in lockstep. This implies that
control logic in each sensor is in exactly the same state as its pair on every clock. To
ensure this, all inputs that affect control logic must be identical and arrive at the same
time at each sensor.
These inputs include:
system clock
system reset
two-wire serial interface clk - SCL
two-wire serial interface data - SDA
Figure 8: Two-Wire Serial Interface Configuration in Stereoscopic Mode
The setup in Figure 8 shows how the two sensors can maintain lockstep when their
configuration registers are written through the two-wire serial interface. A WRITE to
configuration registers would either be broadcast (simultaneous WRITES to both
sensors) or individual (WRITE to just one sensor at a time). READs from configuration
registers would be individual (READs from just one sensor at a time).
One of the two serial interface slave address bits of the sensor is hardwired. The other is
controlled by the host. This allows the host to perform either a broadcast or a one-to-
one access.
Broadcast WRITES are performed by setting the same S_CTRL_ADR input bit for both
slave and master sensor. Individual WRITES are performed by setting opposite
S_CTRL_ADR input bit for both slave and master sensor. Similarly, individual READs are
performed by setting opposite S_CTRL_ADR input bit for both slave and master sensor.
