Programmable Capacitive Tuning IC 8-Pin SON

The CTST570 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 CTST570 is designed to be a labor and cost saving device within the oscillator production process.
