DSC557-05
Crystal-less™ Four Output PCIe Clock Generator
General Description
The DSC557-05 is a Crystal-less™, four output PCI express clock generator meeting Gen1, Gen2, and Gen3 specifications. The clock generator uses proven silicon MEMS technology to provide excellent jitter and stability over a wide range of supply voltages and temperatures. By eliminating the external quartz crystal, MEMS clock generators significantly enhance reliability and accelerate product development, while meeting stringent clock performance criteria for a variety of communications, storage, and networking applications.
DSC557-05 has an Output Enable / Disable feature allowing it to disable all outputs when OE1 and OE2 are low. Each output enable pin controls two banks of synchronous PCIe clocks.
