Part Number: PCM1690 Tool/software: Hello,
Please can I have some advice on PCM1690. In our implementation we are finding that PCM1690 emits a small click when the I2S data is halted (BCK, LRCK & DIN1-4 stopped, SCKI still running). I've attached a…
Part Number: PCM1690 Tool/software: Dear,
Customers using PCM1690 often experience; After changing the following configuration, the probability decreases and only exists at the moment of startup, duration of about 30 seconds;
Change the automatic…
Part Number: PCM1690 Tool/software: Hello. I have designed a PCB with the PCM1690. It has four I2S inputs from DSP, and it uses four of its output channels (the DSP configures the signals to be mono, so the other channels are not required). There is a…
