Functional Description and Application
This integrated circuit permits the design of TV-tuners covering the entire frequency
range from 48 ... 900 MHz split into 2 parts with 3 frequency bands.
The application is suitable for all tuners in TV-and VCR-sets.
Circuit Description
This IC includes 2 balanced mixers (double balanced mixer/ring mixer), two balanced
oscillators for VHF (I and II) and UHF, a reference voltage source and band switch.
Filters between tuner input and IC separate the TV-frequency signal into two bands. The
band switch ensures that only one band at a time is activated. In the activated band the
signal passes a frontend stage with MOSFET-amplifier, a double-tuned bandpass filter
and is then fed to the activated balanced mixer input of the IC which is a low-impedance
stage for the VHF- and UHF-range, respectively.
The input signal is mixed there with the oscillator signal from the activated oscillator
section and fed to a common IF-stage for all bands.
