REN557G-05ALFT
Overview
The 557G-05ALFT is a specialized spread-spectrum clock generator designed to provide high-speed differential clock outputs for PCI-Express applications. It operates from a 3.3V supply and features a 20-pin TSSOP package, offering a compact solution for reducing electromagnetic interference (EMI) in high-speed digital systems.
Why Choose This Part
The device includes integrated spread-spectrum capability which significantly lowers peak EMI by modulating the clock frequency. It provides a dedicated Power Down pin to reduce current consumption to 500 uA and an Output Enable pin for tri-stating outputs during system testing or low-power states.
Applications
Getting Started
Ensure a stable 3.3V supply (3.135V to 3.465V) and follow high-speed PCB layout guidelines for the differential pairs. Use the external selection pins to configure the desired spread percentage and frequency settings according to the datasheet logic tables.
