Device Overview

Summary

The DSC557-03 is a crystal-less, two output PCI express clock generator meeting Gen1, Gen2, Gen3 and Gen4  specifications. The clock generator uses proven silicon MEMS technology to provide 100MHz differential output clocks with excellent jitter and stability over a wide range of supply voltages and temperatures. By eliminating the external quartz crystal, the DSC557-03 significantly enhances reliability and accelerates product development, while meeting stringent clock performance criteria for a variety of communications, storage, and networking applications.DSC557-03 has an Output Enable/Disable feature allowing it to disable the outputs when OE is low. The device is available in two different packages; a space saving 14 pin QFN (77% less board space) or a 16 pin TSSOP that is “drop-in” replacement to exisiting ICS557-03 clock. Additional output formats are also available in any combination of LVPECL, LVDS, and HCSL.

Additional Features
  • Meets PCIe Gen1, Gen2, Gen3 & Gen4 specs
  • MEMS based clock generator eliminates the need for external 25MHz crystal
  • Dual HCSL Clock Output at 100MHz
  • Industry's widest 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 in14-Pin QFN at 3.2x2.5 mm
  • Excellent shock and vibration immunity
  • High reliability
  • Supply Range of 2.25V to 3.6V
  • Lead Free & RoHS Compliant
