This product can be used in series or shunt configuration to support a wide variety of tuning circuit topologies. Digitally controlled capacitance trimming information is municated via a 2-wire, I2C Fast-mode patible interface. The preferred power-up default capacitance value can be stored in the internal, re-programmable, non-volatile memory.
