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.
