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 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…
Dear Jeff:
We tried to reconnect wires between the PDM microphone and the EVB and reconfigure PPC3 software and test again.
It works and we can record correct voice by using external PDM microphone based on the 16 bits,I2S and 48KHz sampling rate.
PCMD3140…
