Hi Team,
CIS output is DC signal and the output range is about 800mV.
Now we use SH2b working mode. We refer to the 0638.LM98620_register_example_Dec2020.pdf that reg 01 with value 48, reg 23 with value 00.
The schematic is attached here. Please note that R13 is not soldered.原理图.pdf
The process is as below:
Power on (OVP high state)-> write value ee to reg 00 and open AIB and PIB -> wait 20ms-> write 2e to reg 00->configurate other register-> input period CLP and work
Issue: using test pattern mode, output OK.
When changing to normal mode, the output data are all 0. And the the data will increase with the time. Try to input a certain voltage to analog input. the output is not related to the input.
Could you kindly help on this issue？
