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 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).

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.

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

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

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

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

=25to0°C or from T

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

“IC Package Databook”

our

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

(order code 9398 652 90011).

TDA5636; TDA5637

SSOP Wave soldering isnot 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).

ETHOD (SO AND SSOP)

M 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. 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.

Repairing soldered joints

Fix the component by first soldering two diagonally-

opposite 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.
