DSC2311KI2-R0049

Crystal-less™ Configurable Clock Generator

General Description

Features

DSC2311KI2-R0049 is a crystal-less clock generator

that is factory configurable to simultaneously output

two separate frequencies from 2.3 to 170MHz. 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

• Two simultaneous LVCMOS outputs:

- 33.333333MHz

• Low RMS phase jitter: <1ps (typical)

• ±25ppm frequency stability

• -40°C to +85°C industrial temperature range

• High supply noise rejection: -50dBc

• High shock & vibration immunity

- Qualified to MIL-STD-883

• High reliability

- 20x higher MTBF than crystal-based clock

generator designs

enhance reliability

and

accelerate

product

development, while meeting stringent clock

performance criteria for a variety of consumer

electronics, communications, and storage applications.

DSC2311KI2-R0049 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

2.5mm x 2.0mm TDFN package that needs only a

single external bypass capacitor. This requires a PCB

footprint equivalent to that of a 1.0mm x 1.0mm

crystal-based clock generator.

• Programmable output strength for EMI reduction

and signal integrity optimization

• Supply range of 2.25 to 3.6V

• AEC-Q100 automotive qualified

• 6-pin 2.5mm x 2.0mm TDFN package

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

• Automotive
