FEATURES
Mobile (reduced pincount) version of PCK2001
Typically used to two SDRAM DIMMs
28 pin SSOP package
Same general features as PCK2001
See PCK2001 for 48-pin 1-18 buffer part supporting up to 4
SDRAM DIMMs
Optimized for 66MHz, 100MHz and 133MHz operation
175 ps skew outputs

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.
