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.
Additional Features
Three 100 MHz HCSL Clock Outputs
Meets PCIe Gen1/2/3/4 clok specs
MEMS based clock generator eliminates the need for external 25MHz crystal
Industry's Widest Operating Temperature Range:
Ext. Industrial: -40°C to 105°C
Industrial: -40°C to 85°C
Ext. Commercial: -20°C to 70°C
Short lead time: 2 weeks
Space Saving 20-Pin QFN package at 5.0x3.2 mm
Qualified to MIL-STD-883
Supply Range of 2.25V to 3.6V
Lead Free & RoHS Compliant
