The analog section of a Bluetooth audio SoC is where careful design pays off. Notes from the JieLi AC695N/AC696N guide:

For the DAC outputs, they recommend reserving positions for small inductors (100nH, 120nH, 220nH, 330nH) to form filters that can suppress high-frequency noise, specifically called out as TDD noise from a nearby mobile phone during calls.

For the #electronics and #embedded crowd: a concise summary of the hardware design guide for JieLi AC695N/AC696N Bluetooth audio SoCs.

It offers crucial DFM advice: you MUST provide test points for the programming pins (USB, power), as the small QFN package necessitates programming after SMT assembly via a USB connection.
