Description
DSC2141 DSC2241
Low-Jitter I2C/SPI Programmable Dual HCSL-CMOS Oscillator
General Description
The DSC2141 and DS2241 series of programmable, high-performance oscillators with HCSL & CMOS outputs utilize a proven silicon MEMS technology to provide excellent jitter and stability while incorporating high output frequency flexibility. DSC2141 and DSC2241 allow the user to independently modify the frequency of each output using I2C or SPI interface, respectively. User can also select from two pre-programmed default output frequencies using the control pin.
DSC2141 and DSC2241 are packaged in 14pin 3.2x2.5 mm QFN packages and available in temperature grades from Ext. Commercial to Industrial.
