VCXO Module IC

The CF5073 series are VCXO ICs with built-in varicap Diode They use a recently developed negative-resis- tance switching oscillation circuit, at oscillation startup and during normal oscillation, for both good oscilla- tion startup characteristics and wide pullrange. Furthermore, it employs a CMOS process varicap Diode and also features all the necessary VCXO structure circuit components on a single chip, forming a VCXO module with just the connection of an external crystal.
