DSC557-0344FI1 Products

The DSC557-0344FI1 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 DSC557-0344FI1 significantly enhances reliability and accelerates product development, while meeting stringent clock performance criteria for a variety of communications, storage, and networking applications.DSC557-0344FI1 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.

Discera, Inc. a leading provider of silicon timing technology, today announced the DSC557-03, the world�s first family of crystal-less PCIe Clock Generators, is shipping in volume production. The DSC557-0344FI1 is a crystal-less, two-output PCI express clock generator meeting Gen1, Gen2, and Gen3 specifications. It uses proven silicon MEMS technology to provide a PCIe compliant 100MHz differential output clocks with excellent jitter and stability over a wide range of supply voltages and temperatures. �MEMS-based technology enables the Company to continue to deliver innovative products with ease of implementation and system cost savings in mind,� said Bruce Diamond, President and CEO of Discera. �Discera is committed to provide best-in-class product innovations, rather than following the industry�s trends in developing crystal-based clock generators. According to our competitive analysis, this family of products delivers on that promise.� Design flexibility is another benefit of Discera�s MEMS-based products. By eliminating the external quartz crystal, caps and tuning resistor, the DSC557-0344FI1 significantly enhances reliability and accelerates product development, while meeting stringent clock performance criteria for a variety of communications, storage, embedded and networking applications. Jitter, temperature range, power consumption and a variety of available output formats are important design considerations for components designed for communications, storage and networking, and designers need the products that provide best in class capabilities in each category, see below. And by eliminating the need for a crystal and other components, system board designers can reduce cost and board size.
