DSC1101/21

Low-Jitter Precision CMOS Oscillator

Features

General Description

• Low RMS Phase Jitter: <1 ps (typ.)

The DSC1101 and DSC1121 series of high

performance oscillators utilize 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:

- Automotive: –55°C to +125°C

- Ext. Industrial: –40°C to +105°C

- Industrial: –40°C to +85°C

- Commercial: –20°C to +70°C

• High Supply Noise Rejection: –50 dBc

• Wide Freq. Range: 2.3 MHz to 170 MHz

• Small Industry Standard Footprints

DSC1101 has a standby feature that allows 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

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

standard 4-pin CMOS 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

Functional Block Diagram

• Supply Range of 2.25 to 3.6V

• Standby and Output Enable Function

• Lead-Free and RoHS Compliant

Applications

• Storage Area Networks

- SATA, SAS, Fibre Channel

• Passive Optical Networks

- EPON, 10G-EPON,V GPON, 10G-PON

• Ethernet

- 1G, 10GBASE-T/KR/LR/SR, and FCoE

• HD/SD/SDI Video and Surveillance

• PCI Express

• Display Port
