7.2.1
Power supplies
The CHR71000 image sensor needs six separate power supplies. Table 7 shows the typical
values for the different power supplies.
The typical current is what a typical sensor draws during idle and read out. The peak currents
drawn are mostly during ROT and should be countered with enough decoupling capacitors.
We recommend one 100µF bulk capacitor at the regulator side and one 100nF local capacitor
per supply pin (not plane!), close to the sensor pins.
7.2.2
Biasing
For optimal performance, some pins need to be decoupled to ground or a Vdd. Please refer to
the pin list for a detailed description for every pin and the appropriate decoupling if applicable.
The table below gives an overview of the external I/O and power pins used to drive the sensor.
