PCK2001
Datasheet
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 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
- 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
