NCD2400M (Data Sheet Rev. 1) The NCD2400M is a dedicated electronic calibrator for oscillators, with reliable performance at 105ºC 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.

NCD2400M Features include:

• Very small package: 2mm x 2mm DFN
• Wide nominal capacitance range: 1.7pF to 194pF
• Smallest switchable capacitor: 355fF
• Wide operating temperature range: -40°C to +105°C

NCD2100 (Data Sheet Rev. 3) The NCD2100 is an EEPROM based digitally programmable variable capacitor that provides capacitive offset trimming for capacitance sensitive circuits. Programming the
non-volatile EEPROM register value or implementing on demand capacitance value changes are easily accomplished by means of the simple two-wire serial bus.

NCD2100 Features include:

• Very small package: 2mm x 2mm DFN package
• Wide nominal capacitance range: 6.6pF to 37.553pF
• Smallest switchable capacitor: 0.063pF
• Minimal nominal current draw: I_DD=1µA
• Wide operating temperature range: -40°C to +85°C
