Block Diagram
Table 22-2.
The USBB provides a hardware device to interface a USB link to a data flow stored in a dual-port
RAM (DPRAM).
The USBB requires a 48MHz ± 0.25% reference clock, which is the USB generic clock gener-
ated from one of the power manager oscillators, optionally through one of the power manager
PLLs.
The 48MHz clock is used to generate a 12MHz 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.
