APPLICATIONS
Cable tuners for TV and VTR; switched concept for VHF
Recommended RF bands for Europe:
48.25 to 105.25 MHz, 112.25 to 294.25 MHz and
471.25 to 855.25 MHz
Recommended RF bands for the USA:
55.25 to 133.25 MHz, 139.25 to 361.25 MHz and
367.25 to 801.25 MHz.
TDA5632; TDA5633
DESCRIPTION
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).
