does increasing the frequency of the clkin oscillator from (24 MHz to 30 MHz)increase the data rate(USB speed) in USB device mode.I am using a customised board with bf548 PROCESSOR (WITH A 25 MHz crystal) and a seperate crystal mounted for USB otg
Increasing the USB clkin from 24 to 30 MHz will only result in less jitter. It will not increase data rate since the output frequency of the USB PLL will need to be same regardless of what input clock you use. Please refer to the USB PLL OSC Control in page 26-142 of the Hardware Reference Manual
