Frequency Generator with 133MHz Differential CPU Clocks
TM
Frequency Generator with 133MHz Differential CPU Clocks
PD# - Assertion (transition from logic "1" to logic "0")
When PD# is sampled low by two consecutive rising edges of CPU clock then all clock outputs except CPU clocks must be
held low on their next high to low transition. CPU clocks must be held with the CPU clock pin driven high with a value of 2x Iref,
and CPUC undriven. Note the example below shows CPU = 100MHz, this diagram and description is applicable for all valid
CPU frequencies 66, 100, 133, 200MHz.
Due to the state of the internal logic, stopping and holding the REF clock outputs in the LOW state may require more than one
clock cycle to complete.
