Overview

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.
See the OE function diagram for more detail.
The device is available in a 20 pin QFN.
Additional output formats are in any combination of LVPECL, LVDS, and HCSL.
Features  Meets PCIe Gen1, Gen2 & Gen3 specs  ...
