DSC1101 DSC1121 Low-Jitter Precision CMOS Oscillator General Description Features The DSC1101 & DSC1121 series of high Low RMS Phase Jitter: <1 ps (typ) performance oscillators utilizes a proven High Stability: 10, 25, 50 ppm silicon MEMS technology to provide excellent jitter and stability over a wide range of Wide Temperature Range supply voltages and temperatures. By o Automotive: -55 to 125 C eliminating the need for quartz or SAW o Ext. Industrial: -40 to 105 C technology, MEMS oscillators significantly o Industrial: -40 to 85 C enhance reliability and accelerate product o Ext. commercial: -20 to 70 C development, while meeting stringent clock performance criteria for a variety of High Supply Noise Rejection: -50 dBc communications, storage, and networking Short Lead Time: 2 Weeks applications. Wide Freq. Range: 2.3 to 170 MHz DSC1101 has a standby feature allowing it to Small Industry Standard Footprints completely power-down when EN pin is o 2.5x2.0, 3.2x2.5, 5.0x3.2, & 7.0x5.0 mm pulled low; whereas for DSC1121, only the outputs are disabled when EN is low. Both Excellent Shock & Vibration Immunity oscillators are available in industry standard o Qualified to MIL-STD-883 2 packages, including the small 3.2x2.5 mm , High Reliability and are drop-in replacements for standard o 20x better MTF than quartz oscillators 4-pin CMOS quartz crystal oscillators. Low Current Consumption Supply Range of 2.25 to 3.6 V Block Diagram Standby & Output Enable Function Lead Free & RoHS Compliant Applications Storage Area Networks o SATA, SAS, Fibre Channel Passive Optical Networks o EPON, 10G-EPON, GPON, 10G-PON Ethernet o 1G, 10GBASE-T/KR/LR/SR, and FCoE Output Enable Modes HD/SD/SDI Video & Surveillance EN Pin DSC1101 DSC1121 PCI Express High Output Active Output Active DisplayPort NC Output Active Output Active Low Standby Output Disabled ______________________________________________________________________________________________________________________________________________ DSC1101 | DSC1121 Page 1 MK-Q-B-P-D-110410-01-6 Low-Jitter Precision CMOS Oscillator DSC1101 DSC1121 Absolute Maximum Ratings Ordering Code Item Min Max Unit Condition Temp Range E: -20 to 70 Supply Voltage -0.3 +4.0 V Enable Modes Packing I: -40 to 85 0: Enable/Standby T: Tape & Reel L: -40 to 105 Input Voltage -0.3 V +0.3 V DD 2: Enable/Disable : Tube M: -55 to 125 Junction Temp - +150 C Storage Temp -55 +150 C DSC11 0 1 C I 5 125.0000 T - Soldering Temp - +260 C 40sec max.
