DSC2311

Crystal-less™ Configurable Two Output Clock Generator

General Description

The DSC2311 is a crystal-less clock

generator that is factory configurable to

simultaneously

output

two

separate

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

supply voltages and temperatures.

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 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.

Features



Two Simultaneous CMOS Outputs:

Output 1 Range: 2.3 to 170 MHz

Output 2 Range: 2.3 to 170 MHz



Low RMS Phase Jitter: <1 ps (typ)



High Stability: ±25, ±50 ppm



Wide Temperature Range

Automotive: -55° to 125° C

Ext. Industrial: -40° to 105° C

Industrial: -40° to 85° C

Ext. commercial: -20° to 70° C



High Supply Noise Rejection: -50 dBc



High Shock & Vibration Immunity

Qualified to MIL-STD-883



High Reliability

20x higher MTBF than crystal-based

clock generator designs



Supply Range of 2.25 to 3.6 V



Lead Free & RoHS Compliant
