9 V VHF, hyperband and UHF mixers­oscillators for TV and VCR 3-band tuners

TDA5636; TDA5637

FEATURES

• Balanced mixer with a common emitter input for band A
(single input)

• 2-pin oscillator for bands A and B

• Balanced mixer with a common base input for

bands B and C (balanced input)

• 4-pin oscillator for band C

• Local oscillator buffer output for external prescaler

• SAW filter preamplifier with a low output impedance to
drive a 75 Ω load

• Band gap voltage stabilizer for oscillator stability

• Electronic band switch

• External IF filter between the mixer output and the IF

amplifier input

• Pin to pin compatible with TDA5636B; TDA5637B family
(same function with symmetrical IF output).

APPLICATIONS

• 3-band all-channel TV and VCR tuners

• Any standard.

GENERAL DESCRIPTION

The TDA5636 and TDA5637 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.17, with the following RF bands:

• 48.25 to 168.25 MHz

• 175.25 to 447.25 MHz

• 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.

These circuits belong to the TDA5636B/TDA5637B family
which has exactly the same function with an IF amplifier
having a symmetrical IF output to drive a SAW filter
directly. It is possible to build tuners with either an
asymmetrical or a symmetrical IF output with one main
tuner lay-out.
