Littelfuse, Inc. Non-volatile, wide capacitance range, digital programmable capacitor NCD2400M

The NCD2400M is a dedicated electronic calibrator for oscillators, with reliable performance at 105°C as required by OCXO applications. This product can be used in series or shunt configuration to support a wide variety of tuning circuit topologies. Digitally controlled capacitance trimming information is communicated via a 2-wire (I2C compatible) interface. The calibration value can be stored in the internal, re-programmable, non-volatile memory.
