Part Number: PCMD3140 Tool/software: I am able to make rather high SNR 4-mic recordings using the EVM (verified with my algorithm, as a first smoke test). Audio sounds good when listening to the WAV.
However, CH 3/4 amplitudes are always 6 dB more than…
Part Number: PCMD3140 Tool/software: Does MCLK really have to be one of the 8 frequencies listed? It seems a bit strange given that the part has a PLL, and I do plan to use the PLL, as the DS says it is required for best performance.
I am master mode…
Part Number: PCMD3140 Other Parts Discussed in Thread: DS90LT012A Tool/software: Hello TI,
I'm a new audio designer, and now I'm designing a circuit of convertering the PDM to I2S but with long lines which exceed 20 cm. I selected the PCMD3140 here and…
Part Number: PCMD3140 Other Parts Discussed in Thread: PCMD3180 Tool/software: Hi,
I'm trying to use the converter above in I2S output configuration together with four PDM mics .
The converter output data is collected by a miniDSP MCHStreamer , set to…
Part Number: PCMD3140 Other Parts Discussed in Thread: PCMD3180 Tool/software: Hello E2E Team,
We have a new design which requires the synchronized sampling of 16 PDM microphones.
In our design the sample rate of each Mic should be 48Khz with a sample…
The setup for our PCMD3140 taking from here ADCx120EVM-PDK, PCMD3140EVM-PDK Evaluation Module page 11(we are using only PCMD3140 without AC-MB)

We connected the I2C channels directly to the Xavier 40-pin header . Additionally, we connected…
Part Number: PCMD3140-Q1 Tool/software: Immediately upon providing power to AVDD and IOVDD, before providing a clock signal to GPIO1 or communicating via I2C, will SDOUT be high, low, or tri-stated?
Thanks.
Part Number: PCMD3140 Hi we have issues at customer with this part, and they are considering that the ground pad has in-sufficient solder. we see about 50% at ground pad, and has a good contact at pins.
please provide feedback on this issue. Xray image…
Part Number: PCMD3140-Q1 Other Parts Discussed in Thread: PCMD3140 Tool/software: I would like to operate the device with the FSYNC frequency slightly (~1-2%) off 96 kHz to synchronize with external devices. Will this pose a problem for the internal operation…
