EURO QUARTZ EMEM1103/1123 - MEMS OSCILLATOR Low Jitter Precision LVDS Oscillator 2.3MHz to 460.0MHz Page 1 of 4 Features Frequency Range 2.3MHz to 460MHz Frequency Stability ±10, ±25 or ±50ppm Operating Voltage: 1.71V to 3.60V Operating Temperature Range Industrial: -40° to +85°C Ext. Commercial: -20° to +70°C High Supply Noise Rejection: -50dBc Short Lead Time Ultra-Miniature Footprints 2.5 x 2.0 x 0.85mm 3.2 x 2.5 x 0.85mm 5.0 x 3.2 x 0.85mm 7.0 x 5.0 x 0.85mm Excellent Shock & Vibration Resistance Qualified to MIL-STD-883 High Reliability Low Current Consumption Supply Voltage from 2.25 to 3.6 Volts Standby and Output Enable Function LVPECL and HCSL versions available Description The Euroquartz EMEM1103 and EMEM1123 series of high performance oscillators utilize MEMS (Micro Electro-Mechanical System) technology, offering excellent jitter and stability performance over a wide range of supply voltages and temperature ranges. The EMEM1103 has a standby feature allowing it to completely power down when the 'EN' pin is pulled low; the EMEM1123 outputs are disabled when EN is low. Both oscillators are available in industry-standard oscillator packages, including the small 2.5 x 2.0mm and are 'drop-in' replacements for standard LVDS output quartz crystal oscillators.
