PCM5122: Differences from PCM5102A

Theodore Salmon

Part Number: PCM5122
Other Parts Discussed in Thread: PCM5102A,

Hello,

From reviewing the datasheets for the PCM5102A and PCM5122, the only difference appears to be that the 5122 has SPI/12C control. Am I correct, or did I miss something?

Furthermore, I understand that Zero Data detection can be fully disabled on the 5122 via the ATMUTECTL register -- if that's correct, the DAC will remain active, right?

I want to switch my design from the 5102A to the 5122 solely so that I can keep the DAC active when no data is being passed from my I2S source.

Thanks!

Hi Ted,

The main difference is that with the additional SPI/I2C control, all the digital features of the device are now accessible. This means that you can access the auto-mute control to disable the automute/zero-detect functionality. In addition you can customize the PLL registers, access the preset process flow, and other digital filter features. It can also support more digital input formats like TDM.

Thanks,
Paul
