General Description

The PCK2001 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.

All clock outputs meet Intel’s drive, rise/fall time, accuracy, and skew requirements.

Key Features

  • HIGH speed, LOW noise non-inverting 1.
  • 18 buffer.
  • Typically used to support four SDRAM DIMMs.
  • Multiple VDD, VSS pins for noise reduction.
  • 3.3V operation.
  • Separate 3-State pin for testing.
  • ESD protection exceeds 2000V per Standard 801.2.
  • Optimized for 66MHz, 100MHz and 133MHz operation.
  • 175 ps skew outputs.
  • Available in 48-pin SSOP package.
  • See PCK2001M for mobile (reduced pincount) 28-pin 1-10 buff.
