Part Number: AMC7834

Hi ,

With context of SPI Interface ,For enabling the DAC Registers in AMC7834 , What is the correct sequence to be followed ?

If i am trying to read the default value of the power mode register (0x02) I am not getting 0x0000. i am getting 0x00000061,but i am able to read and write into the DAC registers .

Please help me with the power-up sequence in the FPGA Level.

Thanks & Regards

Vanitha,

Page 82 of the datasheet goes through a set of initialization steps. Does this help you at all? I would pay particular attention to some of the timing comments to ensure that you are not reading the power mode register too soon and causing some corruption in the read-back.

Otherwise, it sounds like you are able to communicate and verify communication with some registers so it doesn't sound like you would be facing any clock phase or polarity issues or other timing problems.
