The first thing that comes to mind is a parallel out ADC connected to a UART, with a clock generator & dividers to set the baud rate and sample rate. A UART plus parallel DAC can convert from PCM back to analog. There are also stand-alone PCM codecs, eg. https://www.nxp.com/docs/en/data-sheet/MC145483.pdf https://www.analog.com/media/en/technical-documentation/data-sheets/AD74111.pdf
