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.
32
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.
14
VTEST
Input
The user should ground this pin.
23
VRSTLOW
Input
Offset that may be needed for very short exposure conditions.
21
VLN2
Input
Bias setting voltage for the ADC operating current.
39
SDATA
Input/
Output
Serial port data.
30
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.
31
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.
29
EXPOSE
Output
Master mode output signal. Active HIGH during exposure. The two-wire serial
interface register setting switches this pin between input and output.
41
DATA9
Output
Pixel output data bit 9 (MSB).
40
DATA8
Output
Pixel output data bit 8.
45
DATA7
Output
Pixel output data bit 7.
42
DATA6
Output
Pixel output data bit 6.
46
DATA5
Output
Pixel output data bit 5.
47
DATA4
Output
Pixel output data bit 4.
48
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).
12, 22
VAA
Power
3.3V power supply for analog signal processing circuitry.
20
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,
43
VDD
Power
3.3V digital power supply.
4, 5, 28, 34,
35, 44
DGND
Power
Ground for digital circuitry.
