Hi guys,

hope you could help me figuring out, if a allo kali reclocker with its 45.1584 & 49.1520 MHz MCLKs is compatible to the ADAU1701 and if so, which PLL_modes to use (s. Setting the PLL mode for the ADAU1701 at different sample rates ).

I am planning on using audio files with fs = 44.1/48 kHz in case that matters.

Thx,

Max

Hello Max,

No, the Master Clock max frequency is specified in the Digital Timing section as 36ns per clock period. This equates to a max of 27.7MHz.

Explain more what you need to do for your application?
