DESCRIPTION
This part replaces PCK2022R with improved frequency and spread spectrum performance.
The PCK2022RA is a clock synthesizer/driver for a Pentium III™ and other similar processors.
The PCK2022RA has eight differential pair CPU current source outputs, one 33/66 MHz output which is configurable on power-up, 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. All clock outputs meet Intel’s drive strength, rise/fall times, jitter, accuracy, and skew requirements.

FEATURES
• 3.3 V operation
• Eight differential CPU clock pairs

• Power management control pins
• Host clock jitter less than 200 ps cycle-to-cycle
• Host clock skew less than 150 ps pin-to-pin
• Spread Spectrum capability
• Optimized frequency and spread spectrum performance
