Part Number: PCMD3180 Tool/software: Hi,
The customer requires 16 channel synchronous sampling. Can it be achieved by cascading 2pcs and how to handle synchronization issues.
Dear Sanjay:
Sorry for late response.
We followed the test steps as you suggested and finally got correct mic data.
Now we operate in slave mode then we need to externally apply BCLK and FSYNC to the chip.
Steps:
1.Load the I2C as given in datasheet. …
Part Number: PCMD3180 Hi team,
Could you help below?
Thanks!

The PCMD3180 connects 3 microphones and set to TDM slave mode.
There is noise above 8kHz.
How to set the filter…
Part Number: PCMD3180 Hi,
I am posting this on behalf of my team working on a project that involves the recording of ultrasonic sounds using a mems microphone (SPH0641LU4H-1), and PDM to I2S translation of the audio output with the PCM3180. I read in…
Other Parts Discussed in Thread: PCMD3180 Dear Ti member,
The input clock setting now we use is 24.576 MHZ ( 24.576MHz / 48kHz / 16 slots / 32 bits (32x16x48kHz=24.576MHz).) with two PCMD3180.
We are try to set some register to output the PDMCLK on PCMD3180…
Other Parts Discussed in Thread: PCMD3180 Dear TI member,
We're try to buring-up two pcmd3180 for 16 channels TDM output.
Now, it seem only one pcmd3180 TDM out put as below:
Green signal was TDM output.
Yallow signal was FSYNC from SOC.
Then I check…
