SY75578L
PCIe Fanout Buffer
267MHz, 8 HCSL Outputs with 2 Input MUX
PrecisionEdge™
General Description
The SY75578L is a high-speed, fully differential 1:8 clock
fanout buffer optimized to provide eight identical output
copies with 130fs phase jitter and maximum 100ps output-
to-output skew. Designed to be used with PCI-Express
applications, SY75578L accepts HCSL/LVDS and outputs
HCSL logic levels.
The SY75578L 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 32 pin QFN
lead-free package.
The SY75578L 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.
