GENERAL DESCRIPTION
The TDA5737A is a monolithic integrated circuit that
performs the mixer/oscillator functions for
bands A, B and C 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.
This device gives the user the capability to design an
economical and physically small 3-band tuner.
It is suitable for European standards, as illustrated in
Fig.16, with the following RF bands: 48.25 to 168.25 MHz,
175.25 to 447.25 MHz and 455.25 to 855.25 MHz. With
an appropriate tuned circuit, it is also suitable for NTSC all
channel tuners (USA and Japan).
The tuner development time can be drastically reduced by
using this device.
