Status: In Production
The DSC557-04 is a Crystal-less™, three output PCI express clock generator meeting Gen1, Gen2, Gen3 and Gen4 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.DSC557-04 has an Output Enable/Disable feature allowing it to disable all outputs when OE1 and OE2 are low. OE1 controls CLK0 and OE2 controls CLK1/2. CLK1/2 are synchronous PCIe clocks. The device is available in a 20 pin QFN. Additional output formats are in any combination of LVPECL, LVDS, and HCSL.
