DSC2240

DSC2140 DSC2240 Low-Jitter I2C/SPI Programmable HCSL Oscillator Datasheet General Description The DSC2140 and DSC2240 series of programmable, high-performance HCSL oscillators utilizes a proven silicon MEMS technology to provide excellent jitter and stability while incorporating high output frequency flexibility. DSC2140 and DSC2240 allow the user to modify the output frequency using I2C or SPI interface, respectively. User can also select from two pre-programmed default output frequencies using the control pin. DSC2140 and DSC2240 are packaged in 14pin 3.2x2.5 mm QFN packages and available in temperature grades from Ext. Commercial to Industrial.
