W255 200-MHz 24-Output Buffer for 4 DDR or 3 SDRAM DIMMS Features Functional Description • One input to 24-output buffer/driver • Supports up to 4 DDR DIMMs or 3 SDRAM DIMMS • One additional output for feedback • SMBus interface for individual output control • Low skew outputs (< 100 ps) • Supports 266-, 333-, and 400-MHz DDR SDRAM • Dedicated pin for power management support • Space-saving 48-pin SSOP package The W255 is a 3.3V/2.5V buffer designed to distribute high-speed clocks in PC applications. The part has 24 outputs. Designers can configure these outputs to support four unbuffered DDR DIMMS or to support three unbuffered standard SDRAM DIMMs and two DDR DIMMS. The W255 can be used in conjunction with the W250 or similar clock synthesizer for the VIA Pro 266 chipset.
