TDA5731M
The TDA5731M is a monolithic integrated circuit that performs the band A, band B and band C mixer/oscillator functions in TV and VCR tuners. This low power mixer/oscillator circuit requires a power supply of 5 V and is available in a very small package outline. This device gives the designer the capability to design an economical and physically small 3-band tuner. The tuner development time can be drastically reduced by using this device. In addition, when hyperband is not required, the TDA5731M may be used in a VHF/UHF tuner with an appropriate tuned circuit for VHFl and VHFlll in band A and the tuned circuit of band C for UHF.

1. Cross modulation measurement is achieved using the 3 equal signals method (see Fig.4). 2. The gain is defined as the transducer gain (measured in Fig.8) plus the voltage transformation ratio of L7 to L8 (5 : 1, 15.4 dB). 3. The frequency shift is defined as a change in oscillator frequency for a variation of supply voltage. In one instance VP = 5 to 4.75 V and in the other instance VP = 5 to 5.25 V. In both cases, the frequency shift is below the specified value. 4. The frequency ripple susceptibility is measured at 500 kHz at the LO output (see Fig.5). The level of the ripple signal is increased until a difference of 53.5 dB is reached at the IF output. 5. The frequency drift is defined as the change in oscillator frequency for a variation of ambient temperature, on the one hand from Tamb = 25 C to Tamb = 0 C and on the other hand from Tamb = 25 C to Tamb = 50 C. 6. The capacitors in the oscillator circuits of Fig.8 are as follows: a) Band A: C1, C5 and C7. b) Band B: C4 and C9 and C11. c) Band C: C2, C3, C6, C8 and C10 are NP0 types. 7. Switching on drift is the change in oscillator frequency between 5 seconds and 15 minutes after switching on. 8. The values have been corrected for hybrid and cable losses. The symmetrical output impedance of the circuit is 100 . 1995 Mar 21 8

SOLDERING Plastic small outline packages BY WAVE 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. BY SOLDER PASTE REFLOW Reflow soldering requires the solder paste (a suspension of fine solder particles, flux and binding agent) to be DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values

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. REPAIRING SOLDERED JOINTS (BY HAND-HELD SOLDERING
IRON OR PULSE-HEATED SOLDER TOOL)
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.
