DSC2111

DSC2111 DSC2211 Low-Jitter I2C/SPI Programmable Dual CMOS Oscillator Datasheet General Description 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. DSC2111 and DSC2211 are packaged in 14pin 3.2x2.5 mm QFN packages and available in temperature grades from Ext. Commercial to Automotive.
