GENERAL DESCRIPTION
The TDA5630 and TDA5631 are monolithic integrated
circuits that perform the mixer/oscillator functions for
bands A, B and C in TV and VCR tuners. These low-power
mixer/oscillators require a power supply of 9 V and are
available in a very small package.
The devices give the designer the capability to design an
economical and physically small 3-band tuner.
They are suitable for European standards, as illustrated in
Fig.12, 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, they are also suitable for
NTSC all channel tuners (USA and Japan).
The tuner development time can be drastically reduced by
using these devices.
