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.

enabled/disabled individually. An output disabled via the I
interface will be held in the LOW state. In addition, there is an OE
input which 3-states all outputs.
