Audio interface with Agilex 5 A5ED065BB32AI4S

Hi Jyothi, 

Yes — you can use the SSM2518CPZ with an Agilex 5 SoC FPGA — but Agilex5 does not provide a dedicated I²S audio peripheral. That means you need to implement the I²S logic (soft IP) in the FPGA fabric and wire up the codec’s I²S and I²C pins to FPGA/HPS I/O.

You can take community help or use public domain info as there’s no officially documented I²S reference design for Altera SoCFPGA.
