Part Number: PCM2705C Hi,
I am getting pop ad click noise on the earphone when i plug or remove the USB cable. I have designed the Filter circuit as per the datasheet but it's not reducing the noise. The noise gets amplified when I connect the external…
Part Number: PCM2705C Hello,
What kind of internal ESD protection structures are built into the PCM2705C?
We have a board that will be protected inside a metal chassis and the USB cable connected to it will be fixed in place.
The current ESD protection…
My understanding is that the PID can be left alone or modified. The Product Description can also be modified to whatever you want. I do not think you are required to get your own PID and that you can leave it as the default value.
Part Number: PCM2705C Hi
We are developing USB Audio Speaker in which we are using PCM2705C as USB Audio Bridge. As per the Application Diagram, it is recommended to use 100uf coupling electrolyte Cap (C9 and C10 100uF) in the analog output signals…
Part Number: PCM2705C Hi,
I am interested in using the PCM270x to interface USB audio to SPDIF (I intend to use an external DAC). Does the USB/SPDIF signal path within the PCM270x support 24-bit audio? Many thanks.
Regards,
Bernard

What is the frequency of the I2S system clock (pin 18) on PCM2704C/PCM2705C?
Also, are there any recommendations of ferrite bead values and materials to filter the LRCK, BCK, SYSCK and DATA…
Hello, Maurizio,
I think that might work fine as well as you make sure the pull-up resistor is disconnected at the beginning of the PCM2705C operation and connect it until the descriptor is properly programmed.
