HEF4750V Description
The HEF4750V frequency synthesizer is one of a pair of LOCMOS devices, primarily intended for use in high-performance frequency synthesizers, e.g. in all munication, instrumentation, television and broadcast applications. A bination of analogue and digital techniques results in an integrated circuit that enables high performance.
