DESCRIPTION
The PCK2002 is a 1–18 fanout buffer used for 133/100 MHz CPU, 66/33 MHz PCI, 14.318 MHz REF, or 133/100/66 MHz SDRAM clock distribution. 18 outputs are typically used to support up to 4 SDRAM DIMMS commonly found in desktop, workstation or server applications.

FEATURES
• HIGH speed, LOW noise non-inverting 1–18 buffer
• Typically used to support four SDRAM DIMMs
• Multiple VDD, VSS pins for noise reduction
• 3.3 V operation
• Separate 3-State pin for testing
• ESD protection exceeds 2000 V per Standard 801.2
• Optimized for 66 MHz, 100 MHz and 133 MHz operation
• Typical 175 ps skew outputs
• Available in 48-pin SSOP and TSSOP packages
• See PCK2002M for mobile (reduced pincount) 28-pin 1-10 buffer version
• Spread spectrum compliant
• Individual clock output enable/disable via I2C
