DSC2311 Crystal-less Configurable Two-Output Clock Generator Features General Description Two Simultaneous CMOS Outputs The DSC2311 is a crystal-less clock generator that is factory-configurable to simultaneously output two - Output 1 Range: 2.3 MHz to 170 MHz separate frequencies from 2.3 MHz to 170 MHz. The - Output 2 Range: 2.3 MHz to 170 MHz clock generator uses proven silicon MEMS technology Low RMS Phase Jitter: <1 ps (typ.) to provide low jitter and high frequency stability across High Stability: 25 ppm, 50 ppm a wide range of supply voltages and temperatures. By Wide Temperature Range eliminating the external quartz crystal, crystal-less clock generators significantly enhance reliability and - Automotive: 40 C to +125 C accelerate product development, while meeting - Ext. Industrial 40 C to +105 C stringent clock performance criteria for a variety of C to +85 C - Industrial 40 consumer electronics, communications, and storage - Ext. Commercial 20 C to +70 C applications. High Supply Noise Rejection: 50 dBc DSC2311 has an Output Enable/Disable feature that High Shock and Vibration Immunity allows it to disable the outputs when OE is low. The - Qualified to MIL-STD-883 device is available in a space-saving 6-pin 2.5 mm x High Reliability 2.0 mm crystal-less VDFN package that uses only a single external bypass capacitor. This requires a PCB - 20x higher MTBF than crystal-based clock footprint equivalent to that of a 1.0 mm x 1.0 mm generator designs crystal-based clock generator.
