9 V VHF, hyperband and UHF mixersoscillators for TV and VCR 3-band tuners
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 todrive 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).
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.
TDA5636; TDA5637
APPLICATIONS
• 3-band all-channel TV and VCR tuners
• Any standard.
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.
