DSC2140 DSC2240

Low-Jitter I²C/SPI Programmable HCSL Oscillator

General Description

Features

The DSC2140 and DSC2240 series of

 Low RMS Phase Jitter: <1 ps (typ)

 High Stability: ±10, ±25, ±50 ppm

programmable,

high-performance

HCSL

oscillators utilizes a proven silicon MEMS

technology to provide excellent jitter and

stability while incorporating high output

frequency flexibility. DSC2140 and DSC2240

allow the user to modify the output

frequency using I²C or SPI interface,

respectively. User can also select from two

pre-programmed default output frequencies

using the control pin.

 Wide Temperature Range

o Industrial: -40° to 85° C

o Ext. commercial: -20° to 70° C

 High Supply Noise Rejection: -50 dBc

 I²C/SPI Programmable Output Freq

 Short Lead Times: 2 Weeks

 Wide Freq. Range:

o HCSL Output: 2.3 to 460 MHz

DSC2140 and DSC2240 are packaged in 14-

pin 3.2x2.5 mm QFN packages and available

in temperature grades from Ext. Commercial

to Industrial.

 Miniature Footprint of 3.2x2.5mm

 Excellent Shock & Vibration Immunity

o Qualified to MIL-STD-883

 High Reliability

o 20x better MTF than quartz oscillators

Block Diagram

 Supply Range of 2.25 to 3.6 V

 Lead Free & RoHS Compliant

Applications
