Re: [Xylo-SDR] FTDI FT2232C USB interface

[KD5NWA <kd5nwa@cox.net>]

Everyone that mentions the speed of the USB port says it can send up 
to 1 megabyte/Sec, which is a little on the low side if you want to 
do high speed sampling. At 96KHz sampling you are running it at over 
50%, at 192KHz forget it.

I would think that since we can't have drop outs, we should not push 
the chip too close to it's limits. Just an opinion, subject to change 
if proven to be incorrect.
