Part Number: PCMD3180-Q1 We plan to use four PCMD3180-Q1s to connect 32 DMICs and have the following questions.
When the PCMD3180-Q1 is connected to 8 MICs, can PDMCLK1_GPO1 be used to provide PDMCLK to the 8 MICs?
In the I2S wiring, is it sufficient…
Part Number: PCMD3180-Q1 Other Parts Discussed in Thread: PCMD3180 I'm using a Thor SoC and a Linux kernel of 6.8. Below are my device tree modifications. The current problem is that I can't register the sound card. I'm not sure if it's a sound card routing…
Part Number: PCMD3180-Q1 Other Parts Discussed in Thread: PCMX140Q1EVM-PDK , PCM3140-Q1 Tool/software: Hi team,
Do we have a EVM of PCMD3180-Q1?
In the page of the PCMD3180-Q1, it shows the EVM like the following,
However, I think PCMX140Q1EVM…
Part Number: PCMD3180-Q1 Other Parts Discussed in Thread: PCMD3180 Tool/software: Hello Sir,
I use the chip with 8-channel DMIC and connect to NXP's i.MX8M by I2S interface.
I would like to know the signals direction of the FSYNC and BCLK of the PCMD3180…

Part Number: PCMD3180
Tool/software:
I would like to use PCMD3180s to capture 8 PDM Mics at up to 96 kHz (192 kHz would be even better). I found the following thread, but the table in the screenshot is not the same as in the referenced document: PCMD3180…
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:/…
Hi,
For using multiple PCMD3140 devices, we can multiplex the TDM/I2S bus. In order to do so, the TDM/I2S slots in which the devices transmit the data need to be configured independently through I2C register control. Considering the PCMD3140 device…
Hi,
We can cascade up to 4 PCMD3180 ICs as described in section 7.3.1.3 of the datasheet.
We can use up to 4 different I2C addresses for the device (so up to 4 ICs can be independently programmed from a common I2C bus). We can also share the TDM…
