Description

The TDA5634T is an integrated circuit that performs the UHF mixer/oscillator functions in TV and VCR tuners. This low-power mixer/oscillator requires a power supply of 9 V and is available in a very small package.

The TDA5634T gives the designer the capability to design an economical and physically small tuner.

The tuner development time can be drastically reduced by using TDA5634T. The frequency band is determined by the external tank circuit. It can be adapted to various standards.
