DSA557 PCI Express Clock Generators

Microchip Technology DSA557 PCI Express Clock Generators use advanced silicon MEMS technology to generate 100MHz differential clocks with low jitter across varying voltages and temperatures. The Microchip Technology DSA557 replaces quartz and SAW technology, improving reliability and speeding up product development for communication, storage, and networking applications. The DSA557-03/04/05 models offer two, three, and four 100MHz outputs and feature output enable/disable options. The DSA557-03 comes in a compact 14-lead VQFN package, while the DSA557-04 and DSA557-05 are available in a 20-lead VQFN. The devices support multiple output formats, including LVDS and LVCMOS, in addition to the default HCSL output format.
