Description

The TDA5732M is a monolithic integrated circuit that performs VHF I, VHF III, hyperband and UHF mixer/oscillator functions in TV and VCR tuners. This low-power mixer/oscillator requires a power supply of 5 V and is available in a very small package.

The TDA5732M gives the designer the capability to design an economical and physically small 2-band tuner.

The tuner development time of TDA5732M can be drastically reduced by using this device.
