DSC557-054444KE0-EVB

Overview

The DSC557-054444KE0-EVB is a development tool for the DSC557-05 PCIe clock generator. It utilizes silicon MEMS technology to provide four differential 100MHz outputs without an external crystal, enhancing reliability and accelerating product development. The device meets Gen1, Gen2, and Gen3 specifications with mixed output formats including HCSL, LVPECL, or LVDS. It operates on a 2.25V to 3.6V supply within a -20°C to 70°C temperature range.

Feature Summary

• Crystal-less design using proven silicon MEMS technology
• Four differential 100MHz outputs compliant with PCIe Gen1/2/3
• Mixed output format options: HCSL, LVPECL, or LVDS
• Output Enable/Disable feature via OE1 and OE2 pins

Applications

• Communications and Networking (Ethernet, Routers, Switches)
• Storage Systems (SAN, NAS, SSD)
• Embedded Applications (Industrial, Medical, Avionics)

Procurement Notes

Verify the specific evaluation board configuration against project requirements. Confirm that the included hardware supports the desired output format combinations and frequency stability levels. Ensure compatibility with existing test equipment and software tools provided by the manufacturer for proper validation of the clock generator performance.

Selection Notes

Select this evaluation board to prototype designs requiring four synchronized PCIe clocks. Verify that the -20°C to 70°C commercial temperature grade meets system environmental needs. Consider the 20-pin QFN footprint dimensions (5.0 x 3.2 mm) for final PCB layout constraints when transitioning from evaluation to production.

Part Context

This evaluation board supports the DSC557-05 series, which replaces traditional quartz oscillators in PCIe applications. The series offers improved shock and vibration immunity compared to quartz devices. It is designed for communications, storage, and networking systems requiring low jitter and high stability.

Replacement Considerations

For direct component replacements, refer to other DSC557-05 variants with different temperature grades or output formats. Evaluate alternative MEMS clock generators from other manufacturers if specific form factors or pinouts differ from the 20-QFN package.
