USB GCLK @ 48 MHz
USB
The USB controller provides a hardware device to interface a USB link to a data flow stored in a
dual-port RAM (DPRAM).
The USB controller requires a 48 MHz ± 0.25% reference clock, which is the USB generic clock
generated from one of the power manager oscillators, optionally through one of the power man-
ager PLLs.
The 48 MHz clock is used to generate a 12 MHz full-speed (or 1.5 MHz low-speed) bit clock from
the received USB differential data and to transmit data according to full- or low-speed USB
device tolerance. Clock recovery is achieved by a digital phase-locked loop (a DPLL, not repre-
sented), which complies with the USB jitter specifications.
