AZT71
Programmable Capacitive Tuning IC www.azmicrotek.com
DESCRIPTION
The AZT71 is a digitally programmed capacitor specifically designed to
tune a crystal or SAW based oscillator to a desired center frequency. The
desired capacitance value for production trimming is set by a serial data
stream when placed into a programming mode. The AZT71 is designed to
be a labor and cost saving device within the oscillator production process.
Using EEPROM technology, the capacitance can be re-tuned as needed
during the production process by repeating the programming steps
thereby increasing production yield.
The AZT71 is available in an SON8 package (1.5mm x 1.0mm) for very
small form factor oscillators. Also available in MLP6 and TSOT6.
