DSC2122 DSC2222

Low-Jitter I²C/SPI Programmable Dual LVPECL Oscillator

Datasheet

General Description

Features

The DSC2122 and DSC2222 series of

Low RMS Phase Jitter: <1 ps (typ)

High Stability: ±50 ppm

programmable,

high-performance

dual

LVPECL oscillators utilizes a proven silicon

MEMS technology to provide excellent jitter

and stability while incorporating high output

frequency flexibility. DSC2122 and DSC2222

allow the user to independently modify the

frequency of each output 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

Two Independent LVPECL Outputs

I²C/SPI Programmable Frequencies

Short Lead Times: 2 Weeks

DSC2122 and DSC2222 are packaged in 14-

pin 3.2x2.5 mm QFN packages and available

in temperature grades from Ext. Commercial

to Industrial.

Wide Frequency Range:

o LVPECL Output: 2.3 to 460 MHz

Miniature Footprint of 3.2x2.5mm

Excellent Shock & Vibration Immunity

o Qualified to MIL-STD-883

Block Diagram

High Reliability

o 20x better MTF than quartz oscillators

Supply Range of 2.25 to 3.6 V

Lead Free & RoHS Compliant

Applications

Storage Area Networks

o SATA, SAS, Fibre Channel

Passive Optical Networks

o EPON, 10G-EPON, GPON, 10G-PON
