DSC2131 DSC2231  
Low-Jitter I2C/SPI Programmable Dual LVDS-CMOS Oscillator  
General Description  
Features  
The DSC2131 and DSC2231 series of  
programmable, high-performance dual LVDS-  
CMOS oscillators utilizes a proven silicon  
MEMS technology to provide excellent jitter  
and stability while incorporating high output  
frequency flexibility. DSC2131 and DSC2231  
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 Industrial: -40° to 85° C  
o Ext. commercial: -20° to 70° C  
High Supply Noise Rejection: -50 dBc  
Independent LVDS and CMOS Outputs  
I2C/SPI Programmable Freq & Drive  
Short Lead Times: 2 Weeks  
Wide Frequency Range:  
o LVDS Output: 2.3 to 460 MHz  
o CMOS Output: 2.3 to 170 MHz  
DSC2131 and DSC2231 are packaged in 14-  
pin 3.2x2.5 mm QFN package 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  
Block Diagram  
High Reliability  
o 20x better MTF than quartz oscillators  
Supply Range of 2.25 to 3.6 V  
Lead Free & RoHS Compliant
