DESCRIPTION

The PCK2002M is a 1–10 fanout buffer used for 133/100 MHz CPU, 66/33 MHz PCI, 14.318 MHz REF, or 133/100/66 MHz SDRAM clock distribution. 10 outputs are typically used to support up to 2 SDRAM DIMMs commonly found in laptop or mobile applications.

The PCK2002M has the same features and operating characteristics of the PCK2002 and is available in the SSOP 28 pin package.
