Low-Jitter I²C/SPI Programmable Dual CMOS Oscillator

eet

General Description

Features

The DSC2111 and DSC2211 series of

programmable, high-performance dual CMOS

oscillators utilizes a proven silicon MEMS

technology to provide excellent jitter and

stability while incorporating high output

frequency flexibility and drive strength

control. DSC2111 and DSC2211 allow the

user to independently modify the frequency

of each output and CMOS drive strength

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: ±25, ±50 ppm

 Wide Temperature Range

o Automotive: -55° to 125° C

o Ext. Industrial: -40° to 105° C

o Industrial: -40° to 85° C

o Ext. commercial: -20° to 70° C

 High Supply Noise Rejection: -50 dBc

 Two Independent CMOS Outputs

 I²C/SPI Programmable Freq & Drive

 Short Lead Times: 2 Weeks

DSC2111 and DSC2211 are packaged in 14-

pin 3.2x2.5 mm QFN packages and available

in temperature grades from Ext. Commercial

to Automotive.

 Wide Frequency Range:

o CMOS Output: 2.3 to 170 MHz

 Miniature Footprint of 3.2x2.5mm

Block Diagram

 Excellent Shock & Vibration Immunity

o Qualified to MIL-STD-883

 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
