Clock Module
7.1.2
Features of the clock module include:
7.1.3
The PLL operational mode must be configured during reset. The CLKMOD[1:0] package pins
must be driven to the appropriate state for the desired mode from the time RSTOUT asserts until
it negates. Refer to
during reset, the PLL will not default to any mode (so these pins must be hard-tied to power or
ground for desired mode).
The clock module can be operated in normal PLL mode with crystal reference, normal PLL mode
with external reference, 1:1 PLL mode, or external clock mode.

• 8- to 25-MHz reference crystal oscillator
• Current controlled oscillator range from 50 MHz to 150 MHz
• Reduced frequency divider for reduced frequency operation without forcing the PLL to
• Programmable frequency modulation
• Support for low-power modes
• Self-clocked mode operation
