DESCRIPTION
X90100 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.
