CK00 (100/133 MHz) spread spectrum differential system clock generator

The PCK2021 features six differential pair CPU current source outputs, two 33 MHz outputs, one 3V66 output, and two 48 MHz clocks that can be disabled upon power-up, along with one 3.3 V reference clock at 14.318 MHz, also disableable on power-up. It boasts a dedicated power-down input pin for power management, synchronized on-chip for glitch-free output transitions. Additionally, it can be configured to disable 48 MHz outputs for lower power consumption and enhanced performance of functioning outputs. The REF and PCI outputs can also be disabled for optimal Host output performance.
