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 output-
to-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.
