GENERAL 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 device gives the designer the capability to design an
economical and physically small tuner.
The tuner development time can be drastically reduced by
using this device.
The frequency band is determined by the external tank
circuit. It can be adapted to various standards.
