General Description
The SY75572L is a high-speed, fully differential 1:2
clock fanout buffer with a 2:1 input MUX optimized to
provide two identical output copies with 137 fs phase
jitter and a maximum of 50 ps output-to-output skew.
Designed to be used with PCI Express applications, the
SY75572L accepts and outputs HCSL or LVDS logic
levels.
The SY75572L 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
16-pin QFN lead-free package.
The SY75572L is part of Microchip’s high-speed,
ultra-low jitter, PrecisionEdge™ product line. The
SY75572L supports PCIe Gen1-Gen4 requirements.
