Hi all ,
I am working with TLV2556 based EVM. I have been trying very hard to get data from this ADC. The everything looks right (clock , configuration data, CS, eoc) but data out signal is not valid. Some value at reset remain consistent and do not vary according to analog input.
Here I m attaching the DSO image with following legend
1st wave: CS;
2nd wave: DATA IN
3rd wave: CLOCK
4th wave: DATA OUT
