SY75576L

SY75576L 267MHz 1:4 3.3V HCSL/LVDS Fanout Buffer PrecisionEdge™ General Description The SY75576L is a high-speed, fully differential 1:4 clock fanout buffer optimized to provide four identical output copies with 137fs phase jitter and maximum 50ps outputto-output skew. Designed to be used with PCI-Express applications, SY75576L accepts and outputs HCSL or LVDS logic levels. The SY75576L operates from a 3.3V ±5% power supply and is guaranteed over the full industrial temperature range (−40°C to +85°C). It is available in a 20-pin TSSOP lead-free package. The SY75576L is part of Micrel’s high-speed, ultra-low jitter, PrecisionEdge™ product line. Datasheets and support documentation are available on Micrel’s web site at: www.micrel.com.
