DSC1101/21 Low-Jitter Precision CMOS Oscillator Features General Description Low RMS Phase Jitter: <1 ps (typ.) The DSC1101 and DSC1121 series of high performance oscillators utilize a proven silicon MEMS High Stability: 10 ppm, 20 ppm, 25 ppm, technology to provide excellent jitter and stability over 50 ppm a wide range of supply voltages and temperatures. By Wide Temperature Range: eliminating the need for quartz or SAW technology, - Automotive: 55C to +125C MEMS oscillators significantly enhance reliability and - Ext. Industrial: 40C to +105C accelerate product development, while meeting - Industrial: 40C to +85C stringent clock performance criteria for a variety of communications, storage, and networking applications. - Commercial: 20C to +70C High Supply Noise Rejection: 50 dBc DSC1101 has a standby feature that allows it to completely power-down when EN pin is pulled low Wide Freq. Range: 2.3 MHz to 170 MHz whereas for DSC1121, only the outputs are disabled Small Industry Standard Footprints when EN is low. Both oscillators are available in - 2.5 mm x 2.0 mm, 3.2 mm x 2.5 mm, 5.0 mm industry standard packages, including the small x 3.2 mm, and 7.0 mm x 5.0 mm 2.5 mm x 2.0 mm, and are drop-in replacements for Excellent Shock and Vibration Immunity standard 4-pin CMOS quartz crystal oscillators. - Qualified to MIL-STD-883 High Reliability - 20x Better MTF than Quartz Oscillators Functional Block Diagram Low Current Consumption Supply Range of 2.25 to 3.6V Standby and Output Enable Function Lead-Free and RoHS Compliant Applications Storage Area Networks - SATA, SAS, Fibre Channel Passive Optical Networks - EPON, 10G-EPON,V GPON, 10G-PON Ethernet - 1G, 10GBASE-T/KR/LR/SR, and FCoE HD/SD/SDI Video and Surveillance PCI Express Display Port 2017 Microchip Technology Inc.
