General Description
The DSA2311 is a crystal-less™ clock generator that is factory-configurable to simultaneously output two separate frequencies from 2.3 MHz to 170 MHz. The clock generator uses proven silicon MEMS technology to provide low jitter and high frequency stability across a wide range of supply voltages and temperatures. By eliminating the external quartz crystal, crystal-less clock generators significantly enhance reliability and accelerate product development, while meeting stringent clock performance criteria for a variety of consumer electronics, munications, and storage applications.
DSA2311 has an Output Enable/Disable feature that allows it to disable the outputs when OE is low. The device is available in a space-saving 6-lead 2.5 mm x 2.0 mm crystal-less VDFN package that uses only a single external bypass capacitor.
The two output frequencies can be customized by using Clockworks: http://clockworks.microchip./timing
