Tool/software:
Hi experts,
Customer plan to use PCMD3180 for 7 PDM inputs to I2S. Could you please help explain more what are the limitations and workaround solution what if their sampling rate might be greater than 48Khz?
Do we need to use another solution or maybe 2x PCMD3180 could be doable?
Thanks,
Allan
Hi Allan,
You can use this article as a reference for what is supported at certain sampling rates: TLV320ADCx140/PCMx140-Q1 Sampling Rates and Programmable Processing Blocks Supported (Rev. B)
I also answered this question in detail here: https://e2e.ti.com/support/audio-group/audio/f/audio-forum/1449753/pcmd3180-pcmd3180-channel-counts-supported-sample-rates
Let me know if you have any questions.
