DSC2110 Datasheet | Micrel Semiconductor

DSC2110 DSC2210 Low-Jitter I2C/SPI Programmable CMOS Oscillator eet General Description Features The DSC2110 and DSC2210 series of programmable, high-performance CMOS oscillators utilize a proven silicon MEMS technology to provide excellent jitter and stability while incorporating high output frequency flexibility and drive strength control. DSC2110 and DSC2210 allow the user to modify the frequency 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. DSC2110 and DSC2210 are packaged in 14pin 3.2x2.5 mm QFN packages and available in temperature grades from Ext. mercial to Automotive.
