A2B interoptibility with AKM AK7738

Question

Hello, 
 My customer has an AKM AK7738 Audio DSP in their current design. They have added the A2B to their design, but are wondering if ADI has any interoptitbility data for TDM inputs/outputs. i.e. clock polarities, channel configuration, and tri-stating or driving unused channels. Can you help with this?

Hi,

The I2S/TDM port of A2B supports following features:
• Programmable clock and frame sync timing and polarity
• Numerous TDM operating modes
• 16- or 32-bit data width
• Simultaneous operation with PDM port
• Single- or dual-pin input/output (I/O)

For more information, Please refer "Chapter-2, I2S/TDM Interface" and "Chapter-3, I2S/TDM Port Programming Concepts" from AD242x Technical reference manual at below link.

and "Table 7. I2S Timing" from AD242x datasheet at below link.
