Other Parts Discussed in Thread: PCM1861

Dear Team,

My customer would like to use two microphone on Android STB, but their SOC only has I2S interface.

So they are looking for a converter which can transfer I2S to PDM signal.

Do we have such solution?

Thank you.

Hello,

The primary Applications Engineer for this device is currently out of office, returning tomorrow. One of us should be able to reply to your query tomorrow or at least provide an update for an estimated answer given the proximity to the US Thanksgiving Holidays by that time.

Thank you for your patience.

Hi Jim,

The PCM186x devices can handle digital and analog microphone inputs for and convert them to I2S. Take a look at PCM1861 to start.
