W256 - 12 Output Buffer for 2 DDR and 3 SRAM DIMMS

General Description

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.

Key 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.
  • Dedicated pin for power management support.
  • Space-saving 28-pin SSOP package Functional.
