DESCRIPTION

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.

FEATURES

? Non-volatile EEPROM storage of programmed trim codes

? Power On Recall of capacitance setting

? High-Performance Electronically Trimmable Capacitance

? Excellent Linearity: <0.5 LSB error

? Very Simple Digital Interface

? Fast Adjustments: 5μs max incremental change

? Eliminates the need for mechanical tuning

? Capacitance trimmable from 7.5 pF to 14.5 pF (single-ended mode)

? Packages:

—MSOP (1.1mm x 3.0mm x 3.0mm)

—FCP (1.35mm x 1.32mm x 0.50mm)
