Section 3 System Clock Description
The clock is generated by the USB20PHY analog sub-block in the USB20D6E2F module.The Clock and
Reset Generator distributes the internal clock signals for the core and all peripheral modules. Figure
3-1shows the clock connections from the CRG_U to all modules. Consult the CRG_U Block Guide for
details on clock generation.

NOTES:
1. UTMI clock and IQUE clock are fixed 30MHz and 60MHz respectively only when PHY (instead of OSC) is selected as the
clock source. See CRG_U Block Guide for details.
