Hi Expert,
Customer used TS3A5223 to switch analog(NC) and digital(NO) MIC.
The digital MIC clock is output from CODEC MIC2_CLK_7218 into COM1 of TS3A5223.
However, they saw an issue that when using DMIC the measured clock become saw waveform, looks not right.
The clock was confirmed ok by removing R9256.
DS mentioned TS3A5223 can support up to 80Mhz but why it will have this issue with only 3Mhz?
If this somehow relates to COM input capacitance, please suggest us other p2p solutions with lower input capacitance.
Thanks,
Allan
