DSC2131

DSC2131 DSC2231 Low-Jitter I2C/SPI Programmable Dual LVDS-CMOS Oscillator Datasheet General Description The DSC2131 and DSC2231 series of programmable, high-performance dual LVDSCMOS 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. DSC2131 and DSC2231 are packaged in 14pin 3.2x2.5 mm QFN package and available in temperature grades from Ext. Commercial to Industrial.
