PCK2022R Overview
Description
The PCK2022R is a clock synthesizer/driver for a Pentium III™ and other similar processors The PCK2022R 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.
