PCMD3140: Adjusting the drive strength of PDM CLK

Tsugumi Murata

Part Number: PCMD3140

Hello,

Is there a way to adjust the drive strength of the PDM CLK line for PCMD3140?

Currently we are observing some cross-talk noise coupling into PDM DATA line from the PDM CLK edge and we would like to know if the PCMD3140 has the capability to adjust the signal drive strength.

Sincerely,

Tsugumi

Hello Tsugumi,

My apologies for the late response. The PCMD3140 doesn't have any configurations to adjust the drive strength of the pdm clk line.

Regarding your cross-talk issue, could you share a schematic of your application so we could better help?

BR,

Ore
