DESCRIPTION

The PCK2001R is a 1–6 fanout buffer used for 133/100 MHz CPU, 66/33 MHz PCI, 14.318 MHz REF, or 133/100/66 MHz SDRAM clock distribution. 6 outputs are typically used to support up to 4 registered SDRAM DIMMs commonly found in server applications.

FEATURES

•Typically used to support four registered SDRAM DIMMs

•16-pin SSOP package

•See PCK2001 for 48-pin 1:18 buffer part

•See PCK2001M for 28-pin 1:10 buffer part

•Optimized for 33 MHz, 66 MHz, 100 MHz and 133 MHz operation

•Part-to-part skew < 500 ps

•175 ps skew outputs typical

•Individual SDRAM clock output enable/disable via I2C

•Multiple VDD, VSSpins for noise reduction

•3.3 V operation

•ESD protection exceeds 2000 V per Standard 801.2
