USB Audio 2 Maximum Channel limitations
Posted: Tue May 24, 2022 2:01 pm
We are currently running the latest version of the Xmos USB audio 2.0 Reference design. The firmware is running on an XUF216-512. We currently use 6 ADC channels and 2 DAC channels. So we have made some modifications to the firmware. We would ultimately like to use 10 or more USB in/out and 10 or more ADC/DAC I2S channels. We would Support sample rates up to 192 kHz and S/PDIF.
1: Are there any special considerations or limitations in the firmware or timing (or hardware) that we must keep in mind to run this many channels?
2: What is the maximum number of channels that can be supported in this configuration.?
We are prepared to move to a larger device to support the pin count that might be required for all of these I2S pins.
Thanks for any help,
