Overview
The Cypress W40S11-23 is a low-voltage, thirteen-output clock buffer. Output buffer impedance is approximately 15Ω, which is ideal for driving SDRAM DIMMs.

Features
• Thirteen skew-controlled CMOS clock outputs (SDRAM0:12)
• Supports three SDRAM DIMMs
• Ideal for high-performance systems designed around Intel’s latest chip set
• SMBus serial configuration interface
• Clock Skew between any two outputs is less than 250 ps
• 1- to 5-ns propagation delay
• DC to 133-MHz operation
• Single 3.3V supply voltage
• Low power CMOS design packaged in a 28-pin, 300-mil SOIC (Small Outline Integrated Circuit), 28-pin, 173-mil (Thin Shrink Small Outline Package), and 28-pin, 209-mil SSOP (Small Shrink Outline Package)
