DSC12X2/3/4 High Performance Differential MEMS Oscillators Features General Description Very Low RMS Phase Jitter: <650 fs (typ.) The DSC12x2/3/4 family of high performance oscillators utilizes the latest generation of silicon High Stability: 20 ppm, 25 ppm, 50 ppm MEMS technology that reduces close-in noise and Wide Temperature Range: provides excellent jitter and stability over a wide range - Automotive: 40C to +125C (DSC12x3 of supply voltages and temperatures. By eliminating LVDS Only) the need for quartz or SAW technology, MEMS - Extended Industrial: 40C to +105C oscillators significantly enhance reliability and - Industrial: 40C to +85C accelerate product development, while meeting stringent clock performance criteria for a variety of - Commercial: 20C to +70C communications, storage, and networking applications. Supports LVPECL, LVDS, or HCSL Differential Outputs The DSC12x2/3/4 family features a control function on pin 1 or pin 2 that permits either a standby feature Wide Frequency Range: 2.5 MHz to 450 MHz (complete power down when STDBY is low), output Small Industry-Standard Footprints enable (output is tri-stated with OE low), or a frequency - 2.5 mm x 2.0 mm select (choice of two frequencies selected by FS - 3.2 mm x 2.5 mm high/low). See the Product Identification System - 5.0 mm x 3.2 mm section for detailed information. - 7.0 mm x 5.0 mm All oscillators are available in industry-standard Excellent Shock and Vibration Immunity packages, including the small 2.5 mm x 2.0 mm, and - Qualified to MIL-STD-883 are drop-in replacements for standard 6-pin LVPECL/LVDS/HCSL crystal oscillators. High Reliability - 20x Better MTF than Quartz Oscillators Package Types Supply Range of 2.25V to 3.63V DSC12X2/3/4 Standby, Frequency Select, and Output Enable 6-Lead CDFN/VDFN Functions Lead-Free and RoHS-Compliant OE/STDBY/FS 1 6 VDD Applications Storage Area Networks CLK NC 2 5 Passive Optical Networks 10/100G Ethernet GND 3 4 CLK+ HD/SD/SDI Video and Surveillance PCI Express Gen 1/2/3/4 Display Port NC 1 6 VDD CLK OE/STDBY/FS 2 5 GND 3 4 CLK+ 2019 Microchip Technology Inc.
