TDA5732M

DESCRIPTION

The TDA5732M is a monolithic integrated circuit that performs VHF I, VHF III, hyperband and UHF mixer/oscillator functions in TV and VCR tuners. This low-power mixer/oscillator requires a power supply of 5 V and is available in a very small package.

The device gives the designer the capability to design an economical and physically small 2-band tuner.

The tuner development time can be drastically reduced by using this device.

Notes

1. The RF signal is modulated with 50% AM at 15 kHz: The level of the RF signal is increased until there is a 23 dB difference between the LO carrier and the sideband components.

2. The frequency shift is defined as a variation in oscillator frequency when the supply voltage varies from VP= 5 to 4.75 V or from VP= 5 to 5.75 V.

3. The ripple susceptibility is measured for a 500 kHz ripple at the LO output with the set-up as illustrated in Fig.8. The level of the ripple signal is increased until there is a 53.5 dB difference between the LO carrier and the sideband components.

4. The frequency shift is defined as a variation in oscillator frequency when the supply voltage varies from T

=25°Cto0°C or from T

amb

=25°Cto50°C.

amb

5. The switching on drift is defined as the variation in oscillator frequency between 5 seconds and 15 minutes after switching on.

6. SRF: spurious signal on LO with respect to LO output signal; a) RF voltage level=1V at fi= 55.25 to 225 MHz. b) RF level = 2.5 dBm at fi= 225 to 361.25 MHz. c) RF level = −10 dBm at fi= 367.25 to 801.25 MHz.

SOLDERING Plastic small outline packages

YWAVE

B During placement and before soldering, the component

must be fixed with a droplet of adhesive. After curing the adhesive, the component can be soldered. The adhesive can be applied by screen printing, pin transfer or syringe dispensing.

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

A modified wave soldering technique is recommended using two solder waves (dual-wave), in which a turbulent wave with high upward pressure is followed by a smooth laminar wave. Using a mildly-activated flux eliminates the need for removal of corrosive residues in most applications.

Y SOLDER PASTE REFLOW

Reflow soldering requires the solder paste (a suspension of fine solder particles, flux and binding agent) to be

TDA5732M

applied to the substrate by screen printing, stencilling or pressure-syringe dispensing before device placement.

Several techniques exist for reflowing; for example, thermal conduction by heated belt, infrared, and vapour-phase reflow. Dwell times vary between 50 and 300 s according to 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 min at 45 °C.

EPAIRING SOLDERED JOINTS (BY HAND-HELD SOLDERING

IRON OR PULSE

Fix the component by first soldering two, diagonally opposite, end pins. Apply the heating tool to the flat part of the pin only. Contact time must be limited to 10 s at up to 300 °C. When using proper tools, all other pins can be soldered in one operation within 2 to 5 s at between 270 and 320 °C. (Pulse-heated soldering is not recommended for SO packages.)

For pulse-heated solder tool (resistance) soldering of VSO packages, solder is applied to the substrate by dipping or by an extra thick tin/lead plating before package placement.
