Re: [Xylo-SDR] FTDI FT2232C USB interface

[Bill Tracey <bill@ewjt.com>]

I don't think the 2232 will do the speed we need - the data sheet claims 1 
MByte/sec -- for audio we  need 192 Ksamples/second x 2 channels x 3 
bytes/sample (24 bit, 192 khz stereo) which puts us at 1.152 
MBytes/sec  (9.21 MBits/sec) raw transfer rate needed.  Adding in framing 
overhead and some other control info and we're probably out of 
capacity.    For 16 bit 48 khz it would likely work.

Still a nice device to keep in mind -  I've used 'em for PC Bitbanger 
projects - very easy to use and they come in packages with actual pins!

Cheers,
