I have custom board with AD9164.supplies to the Chip are ok .Does AD9164 needs DAC Clock to communicate to SPI port?
I followed the programing sequence as recommeneded by the datasheet. tested this sequence on AD9164_Eval Board successfully.
but on custom board no repsonse from SPI port either read or write. I know there are many things that can be wrong. but if the supplies are correct and power up sequence is correct what else might cuase DAC to not communicate to the FPGA?
Any valuable input and comments in bringing up the DAC AD9164 is welcome.
