DSC2144 DSC2244

Low-Jitter I²C/SPI Programmable Dual HCSL Oscillator

General Description

Features

The DSC2144 and DS2244 series of

programmable, high-performance dual HCSL

oscillators utilizes a proven silicon MEMS

technology to provide excellent jitter and

stability while incorporating high output

frequency flexibility. DSC2144 and DSC2244

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.

 Low RMS Phase Jitter: <1 ps (typ)

 High Stability: ±50 ppm

 Wide Temperature Range

o Industrial: -40° to 85° C

o Ext. commercial: -20° to 70° C

 High Supply Noise Rejection: -50 dBc

 Two Independent HCSL Outputs

 I²C/SPI Programmable Frequencies

 Short Lead Times: 2 Weeks

DSC2144 and DSC2244 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

 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
