IXYS Integrated Circuits Division, Inc., a wholly owned subsidiary of IXYS Corporation, announced the availability of the NCD2100, non-volatile digital programmable capacitor. The NCD2100 is a dedicated electronic calibrator for capacitance critical circuits, a typical example of which is capacitive offset trimming of a crystal oscillator. Digitally controlled capacitance trimming information is communicated via a two-wire serial bus, with the calibration value stored in the internal, non- volatile memory.
The NCD2100 has a tuning ratio of 5.7:1 and a capacitance range of 6.6 – 37.55 pF in very small 63 femtofarad steps for shunt configuration. The device will retain the programmed capacitance value stored in its internal non-volatile memory, which becomes the ideal solution for trimming purposes. Restoring this memory to its initial factory default code is also possible so that future corrections are possible to manage system variations such as aging or re-tuning processes. Other features include very small size, minimum current draw, wide operating voltage range from 2.5V to 5.5V, and MSL 1 rating.
The NCD2100 is available in the 2mm x 2mm DFN package and also in the 2.8mm x 2.9mm TSOT package.
Typical applications include post-trim voltage-controlled oscillators (VCXOs), crystal oscillators, tunable RF Stages, RFID tags, industrial wireless control, filter banks and capacitive sensor trimming.
