1.6V-‐2.1V
200mA
1A
VDD33
3.3V
3V-‐3.6V
100mA

Vres_h
3.3V
3.0V-‐3.6V
NA
0.5A
See pin list for exact pin numbers for every supply.
3.2 BIASING
For optimal performance, some pins need to be decoupled to ground or to VDD. Please refer to the pin list for a
detailed description for every pin and the appropriate decoupling if applicable.
3.3 DIGITAL INPUT PINS
The table below gives an overview of the external pins used to drive the sensor
Pin name
Description
CLK_IN
Master input clock, frequency range between 5 and
48 MHz
LVDS_CLK_N/P
High speed LVDS input clock, frequency range
between 50 and 480 MHz
SYS_RES_N
System reset pin, active low signal. Resets the on-‐
board sequencer and must be kept low during start-‐
up
FRAME_REQ
Frame request pin. When a rising edge is detected
on this pin the programmed number of frames is
captured and sent by the sensor
SPI_IN
Data input pin for the SPI interface. The data to
program the image sensor is sent over this pin.
SPI_EN
SPI enable pin. When this pin is high the data should
be written/read on the SPI
SPI_CLK
SPI clock. This is the clock on which the SPI runs
(max 48Mz)
T_EXP1
Input pin which can be used to program the
exposure time externally. Optional
T_EXP2
Input pin which can be used to program the
exposure time externally in interleaved high
dynamic range mode. Optional
VIH= 3.0V-‐3.3V
VIL= 0.0V-‐0.3V
