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 DigitalClarity⎯Micron’s 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.
