Datasheet Summary
DSC2120 DSC2220
Low-Jitter I2C/SPI Programmable LVPECL Oscillator
General Description
The DSC2120 and DSC2220 series of programmable, high-performance LVPECL oscillators utilizes a proven silicon MEMS technology to provide excellent jitter and stability while incorporating high output frequency flexibility. DSC2120 and DSC2229 allow the user to modify the output frequency using I2C or SPI interface, respectively. User can also select from two pre-programmed default output frequencies using the control pin.
DSC2120 and DSC2220 are packaged in 14pin 3.2x2.5 mm QFN packages and available in temperature grades from Ext. mercial to Industrial.
