PCK2002M0–300 MHz I2C 1:10 clock buffer

FEA TURES

•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

and VSS pins for noise reduction

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 I enabled/disabled individually. An output disabled via the I interface will be held in the LOW state. In addition, there is an OE input which 3-states all outputs.

C interface is included to allow each output to be

•Spread spectrum compliant

•175 ps skew outputs

•Individual clock output enable/disable via I

NOTES:

1. Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability .

2. The input and output voltage ratings may be exceeded if the input and output current ratings are observed.
