Programmable Capacitive Tuning IC

DESCRIPTION

FEATURES

The AZT71 is a digitally programmed capacitor designed to tune a filter

or a crystal/SAW based oscillator to a desired center frequency. Through

a bank of registers, the capacitance value is set by a serial data stream and

if desired, can be permanently stored in the nonvolatile EEPROM

memory. The AZT71 is designed to be a labor and cost saving device

within the oscillator production process and provide the desired

functionality for tunable filter banks.

•

Capacitive tuning range of

6.6pF to 37.553pF

(See AZT70 for different values)

•

0.063pF minimum step size

Continually programmable

with register or EEPROM data

storage

While incorporating very small step sizes (0.063pF), multiple AZT71

devices can also be used in parallel to obtain higher overall capacitance

values.

•

May be placed in parallel for

greater capacitance values

2.5V to 3.6V supply voltage

The AZT71 is available in an SON8 package (1.5mm x 1.0mm) for very

small form factor designs. Also available in MLP6 and TSOT6.
