Description
Differential serial clock/strobe (positive).
Differential serial clock/strobe (negative).
Asynchronous active LOW reset. When asserted, data output stops
and all internal registers are restored to their factory default
settings. This pin will turn off the digital power domain and is the
lowest power state of the sensor.
VCM driver
VCM_ISINK
VCM_GND
Input/Output VCM Driver current sink output. If not used, it could be left floating.
Input/Output Ground connection to VCM Driver. If not used, needs to be connected
to ground (DGND). This ground must be separate from the other
grounds.

DVDD_1V8
Input/Output High-voltage pin for programming OTPM, present on sensors with
that capability. This pin can be left floating during normal operation.
Supply
Power supply. The domains are specified in the next table. The
brackets indicate the number of individual pins.
There are standard GPI and GPIO pads, two each. Chip can also be communicated to
through the two-wire serial interface.
The chip has three unique power supply requirements: 1.2 V, 1.8 V, and 2.8 V. These are
further divided and in all there are seven power domains and five independent ground
domains from the ESD perspective.
