DESCRIPTION
The PCK2001M 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 PCK2001M has the same features and operating characteristics
of the PCK2001 and is available in the SSOP 28 pin package.
