DSC1101 DSC1121

Low-Jitter Precision CMOS Oscillator

General Description

Features

The DSC1101 & DSC1121 series of high

performance oscillators utilizes a proven

silicon MEMS technology to provide excellent

jitter and stability over a wide range of

 Low RMS Phase Jitter: <1 ps (typ)

 High Stability: ±10, ±25, ±50 ppm

 Wide Temperature Range

o Automotive: -55° to 125° C

o Ext. Industrial: -40° to 105° C

o Industrial: -40° to 85° C

supply voltages and temperatures.

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.

o Ext. commercial: -20° to 70° C

 High Supply Noise Rejection: -50 dBc

 Short Lead Time: 2 Weeks

 Wide Freq. Range: 2.3 to 170 MHz

DSC1101 has a standby feature allowing it to

completely power-down when EN pin is

pulled low; whereas for DSC1121, 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

4-pin CMOS quartz crystal oscillators.

 Small Industry Standard Footprints

o 2.5x2.0, 3.2x2.5, 5.0x3.2, & 7.0x5.0 mm

 Excellent Shock & Vibration Immunity

o Qualified to MIL-STD-883

 High Reliability

o 20x better MTF than quartz oscillators

 Low Current Consumption

 Supply Range of 2.25 to 3.6 V

 Standby & Output Enable Function

 Lead Free & RoHS Compliant
