PCK2001DL

14.318-150 MHz I2C 1:18 clock buffer


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 four SDRAM DIMMS commonly found in desktop, workstation or server applications.

All clock outputs meet Intel?s drive, rise/fall time, accuracy, and skew requirements. An I²C interface is included to allow each output to be enabled/disabled individually. An output disabled via the I²C interface will be held in the LOW state. In addition, there is an OE input which 3-States all outputs.

Features and benefits

  • 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
  • 175 ps skew outputs
  • Available in 48-pin SSOP package
  • See PCK2001M for mobile (reduced pincount) 28-pin 1-10 buffer version
  • Individual clock output enable/disable via I²C

NXP Semiconductors' products are specifically designed and manufactured to be used within the electrical, thermal, mechanical and other parameters set forth in NXP Semiconductors' data sheets. Quality and reliability data provided by NXP Semiconductors, such as MTBF, MSL and FIT, is intended to be a non-binding estimate of product performance based upon diffusion process, history only. It does not imply that any performance levels reflected in such data can be met if the product is operated outside the conditions expressly stated in the latest published data sheet for a device or in your application.
