853-2268 26745

FEATURES

• HIGH speed, LOW noise non-inverting 1:10 buffer

• Mobile (reduced pincount) version of PCK2002

• Typically used to support two SDRAM DIMMs

• 28-pin SSOP and TSSOP packages

• See PCK2002 for 48-pin 1-18 buffer part supporting up to

4 SDRAM DIMMs

• Optimized for 66 MHz, 100 MHz and 133 MHz operation

• Multiple V

DD and VSS pins for noise reduction

• Spread spectrum compliant

• 175 ps skew outputs

• Individual clock output enable/disable via I2C

DESCRIPTION

The PCK2002M is a 1–10 fanout buffer used for 133/100 MHz CPU,

66/33 MHz PCI, 14.318 MHz REF, or 133/100/66 MHz SDRAM

clock distribution. 10 outputs are typically used to support up to

2 SDRAM DIMMs commonly found in laptop or mobile applications.

The PCK2002M has the same features and operating characteristics

of the PCK2002 and is available in the SSOP 28 pin package.

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.
