DESCRIPTION
The PCK2021 is a clock synthesizer/driver for a Pentium III
and
other similar processors.
The PCK2021 has six differential pair CPU current source outputs,
two 33 MHz outputs, one 3V66 output, and two 48 MHz clocks
which can be disabled on power-up, and one 3.3 V reference clock
at 14.318 MHz which can also be disabled on power-up.
The part possesses a dedicated power-down input pin for power
management control. This input is synchronized on chip, and
ensures glitch-free output transitions. In addition, the part can be
configured to disable the 48 MHz outputs for lower power operation
and an increase in the performance of the functioning outputs. The
REF and PCI outputs can also be disabled for the highest
performance of the Host outputs.
