Sampling rate vs. max USB rate
Posted: Mon Sep 09, 2019 8:30 pm
I have a question regarding the sampling rate.
The SDRplay is specified with max 10 MS/s. With 14 bit for each sample and twice of that for I and Q.
This is a data rate of 10 * 14 * 2 = 280 Mbit/s
But the USB 2.0 interface can only transfer 40 Mbit/s maximum.
That looks strange, what is the mistake in my calculation ?
Thanks, Harry
