DESCRIPTION
TDA5632; TDA5633
The TDA5632 and TDA5633 are monolithic integrated
circuits that perform VHF and UHF mixer/oscillator
functions in TV and VCR cable tuners. With correct
oscillator application and by using a switchable inductor to
split the VHF band into two sub-bands, the full VHF/UHF
TV bands can be covered. These low-power
mixers/oscillators require a power supply of 9 V and are
available in a very small package.
The devices provide the designer with the capability to
design an economical and physically small cable tuner.
The tuner development time can be drastically reduced by
using this device.
Frequency bands are determined by the external tank
circuit. They can be adapted to various standards.

Note
1. The limits are related to the tank circuits used in Fig.10 and the intermediate frequency. Frequency bands may be
adjusted by the choice of external components. Another UHF frequency range is available by modifying the tank
circuit. The modification enables the following frequency range:
a) RF frequencies from 361.25 to 801.25 MHz (picture carrier).
b) Oscillator frequencies from 407 to 847 MHz. For this UHF range, L4 = 3 turns (diameter = 3.5 mm).
