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.
•
Optimized for 66MHz, 100MHz and 133MHz operation

NOTES:
1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the
device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to
absolute-maximum-rated conditions for extended periods may affect device reliability.
2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
