5 V VHF, hyperband and UHF mixer/oscillators for TV and VCR 3-band tuners

FEATURES

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

• 2-pin oscillator for band A

• Balanced mixer with a common base input for bands B

and C (balanced input)

• 3-pin oscillator for band B

• 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.

APPLICATIONS

GENERAL DESCRIPTION

The TDA5736 and TDA5737 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 5 V and are available in a very small package.

These 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 and 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.

TDA5736; TDA5737

• 3-band all channel TV and VCR tuners

• Any standard.

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”

Reﬂow soldering

Reflow soldering techniques are suitable for all 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

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.

(order code 9398 652 90011).

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).

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.
