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.
