DSC2311

DSC2311 Crystal-less™ Configurable Two Output Clock Generator General Description The DSC2311 is a crystal-less clock generator that is factory configurable to simultaneously output two separate frequencies from 2.3 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, communications, and storage applications. DSC2311 has an Output Enable / Disable feature allowing it to disable the outputs when OE is low. The device is available in a space saving 6 pin 2.5 x 2.0 mm crystalless TDFN package that uses only a single external bypass capacitor. This requires a PCB footprint equivalent to that of a 1.0 x 1.0 mm crystal-based clock generator.
