Product specication
9 V VHF hyperband and UHF
mixer/oscillator for TV and VCR 3-band
TDA5636B; TDA5637B
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 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
Pin-to-pin compatible with TDA5636; TDA5637 family
(same function with asymmetrical IF output).
APPLICATIONS
3-band all channel TV and VCR tuners
Any standard.
GENERAL DESCRIPTION
The TDA5636B and TDA5637B 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 TDA5636/TDA5737 family
which has exactly the same function with an IF amplifier
having an asymmetrical IF output to drive a 75
load. It is
possible to build tuners with either an asymmetrical or a
symmetrical IF output with one main tuner lay-out.
