DSC2311

Crystal-less™ Configurable Two-Output Clock Generator

Features

General Description

• Two Simultaneous CMOS Outputs

- Output 1 Range: 2.3 MHz to 170 MHz

- Output 2 Range: 2.3 MHz to 170 MHz

• Low RMS Phase Jitter: <1 ps (typ.)

• High Stability: ±25 ppm, ±50 ppm

• Wide Temperature Range

- Automotive: –40^°C to +125^°C

- 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

• High Shock and Vibration Immunity

- Qualified to MIL-STD-883

The DSC2311 is a crystal-less™ clock generator that is

factory-configurable to simultaneously output two

separate frequencies from 2.3 MHz to 170 MHz. The

clock generator uses proven silicon MEMS technology

to provide low jitter and high frequency stability across

a wide range of supply voltages and temperatures. By

eliminating the external quartz crystal, crystal-less

clock generators significantly enhance reliability and

accelerate product development, while meeting

stringent clock performance criteria for a variety of

consumer electronics, communications, and storage

applications.

DSC2311 has an Output Enable/Disable feature that

allows it to disable the outputs when OE is low. The

device is available in a space-saving 6-pin 2.5 mm x

2.0 mm crystal-less VDFN package that uses only a

single external bypass capacitor. This requires a PCB

footprint equivalent to that of a 1.0 mm x 1.0 mm

crystal-based clock generator.

• High Reliability

- 20x higher MTBF than crystal-based clock

generator designs

• Supply Range of 2.25V to 3.6V

• Lead Free and RoHS-Compliant

Applications

• Consumer Electronics

• Camera and Imaging Modules

• Home Automation

• Industrial and Power Conversion

• Mobile Communications, Internet, and Sensor

Devices

• Solid State, Hard Drive, and Flash Drive Storage
