9VREF1

Input

ADC reference voltage that sets the maximum input signal level, setting the

size of the least significant bit (LSB) in the analog to digital conversion process.

8VREF1DRV

Input

ADC bias.

7VREF2

Input

ADC reference used for the calibration operation.

FRAME_SYNC_N

Input

Slave mode input signal. Active low pulse to reset row and column counters,

providing frame synchronization. Low duration should be at least two-clock

cycles wide. An input that is held LOW also sets the sensor in LOW, per standby

mode, until it is released. Signal is pulled up on-chip.

VTEST

Input

The user should ground this pin.

VRSTLOW

Input

Offset that may be needed for very short exposure conditions.

VLN2

Input

Bias setting voltage for the ADC operating current.

SDATA

Input/

Output

Serial port data.

FRAME_VALID

Output

Master mode and snapshot mode output signal. Active HIGH during readout.

The two-wire serial interface register setting switches this pin between input

and output.

ROW_VALID

Output

Master mode and snapshot mode output signal. Active HIGH when image data

are on data output bus. The two-wire serial interface register setting switches

this pin between input and output.

EXPOSE

Output

Master mode output signal. Active HIGH during exposure. The two-wire serial

interface register setting switches this pin between input and output.

DATA9

Output

Pixel output data bit 9 (MSB).

DATA8

Output

Pixel output data bit 8.

DATA7

Output

Pixel output data bit 7.

DATA6

Output

Pixel output data bit 6.

DATA5

Output

Pixel output data bit 5.

DATA4

Output

Pixel output data bit 4.

DATA3

Output

Pixel output data bit 3.

1DATA2

Output

Pixel output data bit 2.

2DATA1

Output

Pixel output data bit 1.

3DATA0

Output

Pixel output data bit 0 (LSB).

VAA

Power

3.3V power supply for analog signal processing circuitry.

VRST_PIX

Power

Power supply for pixel array. Set for 2.5V.

10, 11, 15

AGND

Power

Ground for analog signal processing circuitry.

6, 27, 36,

VDD

Power

3.3V digital power supply.

4, 5, 28, 34,

35, 44

DGND

Power

Ground for digital circuitry.
