The Xicor X90100 is a non-volatile electronically programmable capacitor. The device is programmed through a simple digital interface. After programming, the chosen setting for the device is retained by internal EEPROM storage whether or not DC power is maintained. There are 32 programmable capacitance values selectable, ranging from 7.5 pF to 14.5 pF in 0.23 pF increments, in single-ended mode. The dielectric is highly stable, and the capacitance exhibits a very low voltage coefficient. It has virtually no dielectric absorbtion and has a very low temperature drift coefficient in differential mode (<50ppm/C).
