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 Ω load. It is
possible to build tuners with either an asymmetrical or a
symmetrical IF output with one main tuner lay-out.

Notes

1. The RF frequency range is defined by the oscillator frequency range and the intermediate frequency.

2. The gain is defined as the transducer gain (measured in Fig.17) plus the voltage transformation ratio of L6 to L7
(10 : 2, 15.4 dB including transformer loss).

3. The input level causing 10 kHz frequency detuning at the LO output; f

osc=fRF

+ 33.4 MHz.

4. Limits are related to the tank circuits used in Fig.17. Frequency bands may be adjusted by the choice of external
components.

5. The frequency shift is defined as the change in oscillator frequency when the supply voltage varies from
VP= 9 to 8.1 V and from VP= 9 to 9.9 V.

6. The frequency drift is defined as the change in oscillator frequency when the ambient temperature varies from
T

amb

=25to0°C and from T

amb

= 25 to 50 °C.

7. Switch on drift is defined as the change in oscillator frequency between 5 s and 15 min after switch on.

8. SRF: spurious signal on LO with respect to LO output signal:

RF level = 120 dBµV at fRF< 180 MHz
RF level = 107.5 dBµV at fRF= 180 to 225 MHz
RF level = 97 dBµV at fRF= 225 to 860 MHz.

SOLDERING
Introduction

There is no soldering method that is ideal for all IC
packages. Wave soldering is often preferred when
through-hole and surface mounted components are mixed
on one printed-circuit board. However, wave soldering is
not always suitable for surface mounted ICs, or for
printed-circuits with high population densities. In these
situations reflow soldering is often used.

This text gives a very brief insight to a complex technology.
A more in-depth account of soldering ICs can be found in
our

“IC Package Databook”

(order code 9398 652 90011).

Reflow soldering

Reflow soldering techniques are suitable for all SO and
SSOP packages.

Reflow soldering requires solder paste (a suspension of
fine solder particles, flux and binding agent) to be applied
to the printed-circuit board by screen printing, stencilling or
pressure-syringe dispensing before package placement.

Several techniques exist for reflowing; for example,
thermal conduction by heated belt. Dwell times vary
between 50 and 300 seconds depending on heating
method. Typical reflow temperatures range from
215 to 250 °C.

Preheating is necessary to dry the paste and evaporate
the binding agent. Preheating duration: 45 minutes at
45 °C.

Wave soldering

SO
Wave soldering techniques can be used for all SO

packages if the following conditions are observed:

• A double-wave (a turbulent wave with high upward
pressure followed by a smooth laminar wave) soldering
technique should be used.

• The longitudinal axis of the package footprint must be
parallel to the solder flow.

• The package footprint must incorporate solder thieves at
the downstream end.

SSOP
Wave soldering is not recommended for SSOP packages.

This is because of the likelihood of solder bridging due to
closely-spaced leads and the possibility of incomplete
solder penetration in multi-lead devices.

If wave soldering cannot be avoided, the following
conditions must be observed:

• A double-wave (a turbulent wave with high upward

pressure followed by a smooth laminar wave)
soldering technique should be used.

• The longitudinal axis of the package footprint must

be parallel to the solder flow and must incorporate
solder thieves at the downstream end.

Even with these conditions, only consider wave
soldering SSOP packages that have a body width of

4.4 mm, that is SSOP16 (SOT369-1) or
SSOP20 (SOT266-1).

METHOD (SO AND SSOP)
During placement and before soldering, the package must

be fixed with a droplet of adhesive. The adhesive can be
applied by screen printing, pin transfer or syringe
dispensing. The package can be soldered after the
adhesive is cured.

Maximum permissible solder temperature is 260 °C, and
maximum duration of package immersion in solder is
10 seconds, if cooled to less than 150 °C within
6 seconds. Typical dwell time is 4 seconds at 250 °C.

A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.

Repairing soldered joints

Fix the component by first soldering two diagonally­opposite end leads. Use only a low voltage soldering iron
(less than 24 V) applied to the flat part of the lead. Contact
time must be limited to 10 seconds at up to 300 °C. When
using a dedicated tool, all other leads can be soldered in
one operation within 2 to 5 seconds between
270 and 320 °C.
