Philips Semiconductors
5 V VHF, hyperband and UHF mixers/oscillators
for TV and VCR 3-band tuners
Product specification
TDA5736; TDA5737
FEATURES
Balanced mixer with a common emitter input for band A
(single input)
2-pin oscillator for band A
Balanced mixer with a common base input for bands B
and C (balanced input)
3-pin oscillator for band B
4-pin oscillator for band C
Local oscillator buffer output for external prescaler
SAW filter preamplifier with a low output impedance to
drive the SAW filter directly
Band gap voltage stabilizer for oscillator stability
Electronic band switch
External IF filter between the mixer output and the IF
amplifier input.
GENERAL DESCRIPTION
The TDA5736 and TDA5737 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 5 V and are
available in a very small package.
These 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.17, 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.
APPLICATIONS
3-band all channel TV and VCR tuners
Any standard.

1. The limits are related to the tank circuits used in Fig.17 and the intermediate frequency. Frequency bands may be
adjusted by the choice of external components.
