W256 12 Output Buffer for 2 DDR and 3 SRAM DIMMS

The W256 is a 3.3V/2.5V buffer designed to distribute high-speed clocks in PC applications. The part has 12 outputs. Designers can configure these outputs to support 3 unbuffered standard SDRAM DIMMs and 2 DDR DIMMs. The W256 can be used in conjunction with the W250-02 or similar clock synthesizer f.

W256 Features

* One input to 12 output buffer/drivers

* Supports up to 2 DDR DIMMs or 3 SDRAM DIMMS

* One additional output for feedback

* SMBus interface for individual output control

* Low skew outputs (< 100 ps)

* Supports 266 MHz and 333 MHz DDR SDRAM
