Device Overview

Summary

The DSA557-05 is an automotive grade crystal-less, 4-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 automotive grade 2  ( -40°C to 105°C) temperature range. By eliminating the external quartz crystal, the DSA557-05 significantly enhances reliability and accelerates product development, while meeting stringent clock performance criteria for a variety of automotive applications. DSA557-05 has an Output Enable/Disable feature allowing it to disable the outputs when OE pin is low. The device is a space saving 20 pin QFN  package.
