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)

APPLICATIONS

• Post-trim of low-cost regenerative receivers

• Tunable RF stages

• Low-cost, Low temperature drift oscillators

• Garage door openers

• Keyless entry

• Industrial wireless control

• Capacitive sensor trimming

• RFID tags
