Device Overview

Summary

The DSC2122 and DSC2222 series of 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.DSC2122 and DSC2222 are packaged in 14-pin 3.2mm x 2.5mm QFN packages and available in temperature grades from Ext. Commercial to Industrial.
