1 / 7 page ______________________________________________________________________________________________________________________________________________ DSC1102 | DSC1122 Page 1 MK-Q-B-P-D-110410-02-6 Low-Jitter Precision LVPECL Oscillator DSC1102 DSC1122 General Description The DSC1102 & DSC1122 series of high performance oscillators utilizes a proven silicon MEMS technology to provide excellent jitter and stability over a wide range of supply voltages and temperatures. By eliminating the need for quartz or SAW technology, MEMS oscillators significantly enhance reliability and accelerate product development, while meeting stringent clock performance criteria for a variety of communications, storage, and networking applications. DSC1102 has a standby feature allowing it to completely power-down when EN pin is pulled low; whereas for DSC1122, only the outputs are disabled when EN is low. Both oscillators are available in industry standard packages, including the small 3.2x2.5 mm2, and are “drop-in” replacements for standard 6-pin LVPECL quartz crystal oscillators.
