Re: 48kHz on USB Audo Multichannel Reference Design. How to?

Hi,
you can define the sampling frequency in customdefines.h,like this:

/* Maximum frequency device runs at */
#ifndef MAX_FREQ
#define MAX_FREQ (48000)
#endif

#ifndef MIN_FREQ
#define MIN_FREQ (48000)
#endif

Maby it's OK.

About xCORE200 extending the reference design to higher sample rates

I was a XMOS user form china.I have a few problems about the software reference design,my hardware platforms: XU208-128-c10,software: sw_usb_audio-[sw]_6.15.2rc1. It can good warking at MCLK@512Fs,rates up to 384K/32Bit DOP 128, but when i change to 1024Fs (45.1548M and 49.152M) ,the clock generator...

Re: XU208 resulting in noise when play PCM 705.6KHz/768KHz

Hi, i have the same problem, it's not Jitter is really large, it's BCLK has error stay high in Periodicity, Most of the time is right. The right BCLK is:101010101010101010101010 the error like this : 10101010111101010101010 For the switch (divide) i add #if (MAX_DIVIDE > 16) Mode, ------------------...
