DSC2142 DSC2242

Low-Jitter I²C/SPI Programmable HCSL-LVPECL Oscillator

General Description

Features

The DSC2142 and DSC2242 series of high

performance dual output oscillators utilize a

proven silicon MEMS technology to provide

 Low RMS Phase Jitter: <1 ps (typ)

 High Stability: ±50 ppm

excellent

jitter

and

stability

while

 Wide Temperature Range

o Industrial: -40° to 85° C

o Ext. commercial: -20° to 70° C

incorporating additional device functionality.

DSC2142 and DSC2242 allow the user to

independently modify the frequency of each

output

using

I²C

SPI

interface,

 High Supply Noise Rejection: -50 dBc

 Independent HCSL & LVPECL Outputs

 I²C/SPI Programmable Frequencies

 Short Lead Times: 2 Weeks

respectively. User can also select from two

pre-programmed default output frequencies

using the control pin.

DSC2142 and DSC2242 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 HCSL Output: 2.3 to 460 MHz

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

 Ethernet

o 1G, 10GBASE-T/KR/LR/SR, and FCoE

 HD/SD/SDI Video & Surveillance

 PCI Express
