DSC2311

Crystal-less™ Configurable Two Output Clock Generator

General Description

Features

The DSC2311 is a crystal-less clock

generator that is factory configurable to

 Two Simultaneous CMOS Outputs:

o Output 1 Range: 2.3 to 170 MHz

simultaneously

output

two

separate

Output 2 Range: 2.3 to 170 MHz

frequencies from 2.3 to 170 MHz. The clock

generator uses proven silicon MEMS

technology to provide low jitter and high

frequency stability across a wide range of

 Low RMS Phase Jitter: <1 ps (typ)

 High Stability: ±25, ±50 ppm

supply voltages and temperatures.

 Wide Temperature Range

o Automotive: -55° to 125° C

o Ext. Industrial: -40° to 105° C

o Industrial: -40° to 85° C

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.

o Ext. commercial: -20° to 70° C

 High Supply Noise Rejection: -50 dBc

 High Shock & Vibration Immunity

o Qualified to MIL-STD-883

DSC2311 has an Output Enable / Disable

feature allowing it to disable the outputs

when OE is low. The device is available in a

space saving 6 pin 2.5 x 2.0 mm crystal-

less TDFN package that uses only a single

external bypass capacitor. This requires a

PCB footprint equivalent to that of a 1.0 x

1.0 mm crystal-based clock generator.

 High Reliability

o 20x higher MTBF than crystal-based

clock generator designs

 Supply Range of 2.25 to 3.6 V

 Short Lead Times: 2 Weeks

 Lead Free & RoHS Compliant

Applications

 Consumer Electronics

 Camera and Imaging Modules

 Home Automation
