USB host controller: Clock oscillator instead of a crystal resonator

Latest Updated:02/01/2009

Question:

For the USB host/peripheral controller, can a clock oscillator be used instead of a crystal resonator?

Answer:

An external clock oscillator can be used as long as the clock or PLL is not stopped (i.e., by setting the PWDOWN or GSUSPEND bit to 1).
