PCK2002
Datasheet
General 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.
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
- 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
