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. Commercial to Automotive.
