It accepts a single-ended clock input and fans it out to 13 outputs with minimal skew between channels, maintaining timing margins across the memory bus. The part operates from a 3.135 V to 3.465 V supply and is rated for 133 MHz maximum frequency. It comes in a 28-SOIC surface-mount package with 0.295-inch body width and 7.50 mm lead pitch. ## 133 MHz and 2:13 fanout — what they mean for the BOM The 133 MHz maximum frequency is the clock rate the driver can cleanly propagate; it is not a synthesised output but a buffered version of the input. ## Temperature grade and environment Rated for 0°C to 70°C ambient, this part is intended for commercial indoor equipment — desktop PCs, servers, and telecom line cards where the chassis temperature stays within that band. ## Lifecycle and sourcing posture It is RoHS non-compliant per the manufacturer's declaration, so designs requiring RoHS conformance must verify the exemption or select a compliant variant.","metaTitle":"W40S11-23G Low Skew Clock Driver, 133 MHz, 28-SOIC","metaDescription":"W40S11-23G low skew clock driver for SDRAM DIMM applications. 133 MHz max, 2:13 fanout, 3.3 V supply, 28-SOIC.
