Please provide the power up sequence or pin configuration sequence?
I do not know of any power sequencing requirements for the AD1871. Are you planning on using 3 discrete regulators for AVDD, DVDD and ODVDD? If you are powering the regulators form the same supply, you will be fine. I would recommend that you pull /RESET (pin 24) low during power up and then assert it high after the voltage rails have stabilized. After assertion of the /RESET pin, you can program the registers with your configuration. I would allow for a small number of MCLK cycles to pass after programming before using the part, to allow all of the internal counters to align, maybe 256 or so.
Please let us know if you need more information.
I moved your question to the audio section of our forum, hopefully someone in this group can help you with your question.
