Block Diagram
Table 26-2.
The USBB provides a hardware device to interface a USB link to a data flow stored in a dual-port
RAM (DPRAM).
The UTMI transceiver requires an external 12MHz clock as a reference to its internal 480MHz
PLL. The internal 480MHz PLL is used to clock an internal DLL module to recover the USB dif-
ferential data at 480Mbit/s.
