General Description

The DSA557 series of high performance PCI Express clock generators use a proven silicon MEMS technology to provide 100 MHz differential output clocks with excellent jitter and stability over a wide range of supply voltages and temperatures. By eliminating the need for quartz or SAW technology, MEMS oscillators significantly enhance reliability and accelerate product development, while meeting stringent clock performance criteria for a variety of communications, storage, and networking applications. The DSA557-03/04/05 have two, three, and four 100 MHz outputs, respectively. All have output enable/disable features.
