DSC1123CL5-050.0000T Microchip

DSC1103/23 Low-Jitter Precision LVDS Oscillator Features General Description Low RMS Phase Jitter: <1 ps (typ.) The DSC1103 and DSC1123 series of high performance oscillators utilizes a proven silicon MEMS High Stability: 10 ppm, 25 ppm, 50 ppm technology to provide excellent jitter and stability over Wide Temperature Range: a wide range of supply voltages and temperatures. By - Ext. Industrial 40C to +105C eliminating the need for quartz or SAW technology, - Industrial 40C to +85C MEMS oscillators significantly enhance reliability and - Ext. Commercial 20C to +70C accelerate product development, while meeting stringent clock performance criteria for a variety of High Supply Noise Rejection: 50 dBc communications, storage, and networking applications. Wide Frequency Range: DSC1103 has a standby feature allowing it to - 2.3 MHz 460 MHz completely power-down when EN pin is pulled low. For Small Industry Standard Footprints DSC1123, only the outputs are disabled when EN is - 2.5 mm x 2.0 mm low. Both oscillators are available in industry standard - 3.2 mm x 2.5 mm packages, including the smallest 2.5 mm x 2.0 mm, - 5.0 mm x 3.2 mm and are drop-in replacements for standard 6-pin LVDS - 7.0 mm x 5.0 mm crystal oscillators. Excellent Shock and Vibration Immunity Block Diagram - Qualified to MIL-STD-883 High Reliability - 20x better MTF than quartz-based devices Pin 1 Pin 6 Low Current Consumption Temp.
