ADAU7002 interface to GSM module

I'm working on a project that includes a BGS5 Cinterion GSM module. This module only has a digital audio interface of 16bit 8kHz, which results in a bitclock of 256kHz and a LRclock of 8kHz, (X32).

ADAU7002 requires af differens between the two clocks of X64.

Is it possible to circumvent the X64 demand of the 7002?

Is it possible to get another PDM to PCM converter that will accept a difference ofX32?

Does AD deliver a simple codec that accepts a PDM signal directly?


Thank you
