DSC1102/22

Low-Jitter Precision LVPECL Oscillator

Features

General Description

• Low RMS Phase Jitter: <1 ps (typ.)

The DSC1102 and DSC1122 series of high

performance oscillators utilizes a proven silicon MEMS

technology to provide excellent jitter and stability over

a wide range of supply voltages and temperatures. By

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.

• High Stability: ±10 ppm, ±20 ppm, ±25 ppm,

±50 ppm

• Wide Temperature Range

- Ext. Industrial: –40°C to +105°C

- Industrial: –40°C to +85°C

- Ext. Commercial: –20°C to +70°C

• High Supply Noise Rejection: –50 dBc

• Wide Frequency Range: 2.3 MHz to 460 MHz

• Small Industry Standard Footprints:

DSC1102 has a standby feature allowing it to

completely power down when EN pin is pulled low;

whereas for DSC1122, only the outputs are disabled

when EN is low. Both oscillators are available in

industry standard packages, including the smallest

2.5 mm x 2.0 mm, and are drop-in replacements for

standard 6-pin LVPECL quartz crystal oscillators.

- 2.5 mm x 2.0 mm, 3.2 mm x 2.5 mm,

5.0 mm x 3.2 mm, and 7.0 mm x 5.0 mm

• Excellent Shock and Vibration Immunity

- Qualified to MIL-STD-883

• High Reliability

- 20x Better MTF than Quartz Oscillators

• Low Current Consumption
