PCK2001; 14.318-150 MHz I²C 1:18 Clock Buffer
| 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. 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.
