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 137fs phase jitter and a maximum of 50ps 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 Micrel’s high-speed, ultra-low jitter, PrecisionEdge™ product line. The SY75572L supports PCIe Gen1-Gen3 requirements with sufficient performance margin for pending PCIe Gen4 applications.
