SAA5244A
The Integrated VIP and Teletext (IVT1.1) is a teletext decoder (contained within a single-chip package) for decoding 625-line based World System Teletext transmissions. The teletext decoder hardware is based on a reduced function version of the device SAA5246 (IVT1.0). The Video Input Processor (VIP) section of the device uses mixed analog and digital designs for the data slicer and the display clock phase-locked loop functions. As a result the number of external components is greatly reduced and no critical or adjustable components are required. A single page static RAM is incorporated in the device thereby giving a genuine single-chip teletext decoder device.

1. The human body model ESD simulation is equivalent to discharging a 100 pF capacitor through a 1.5 k resistor; this produces a single discharge transient. Reference Philips Semiconductors test method UZW-B0/FQ-A302 (compatible with MIL-STD method 3015.7). Failure Rate The failure rate at Tamb = 55 C will be a maximum of 1000 FITS (1 FIT = 1 x 10-9 failures per hour).

Notes to the characteristics 1. This current is the maximum allowed into the inputs when line and field flyback signals are connected to these inputs. Series current limiting resistors must be used to limit the input currents to 1 mA. 2. RGBREF is the positive supply for the RGB output pins and it must be able to source the IOH current from the R, G and B pins. The leakage specification on RGBREF only applies when there is no current load on the RGB pins.

Row 0: Row 0 is for the page header. The first seven columns (0 to 6) are free for status messages. The eighth is an alphanumeric white or green control character, written automatically by SAA5244A to give a green rolling header when a page is being looked for. The last eight characters are for rolling time. Row 25: The first 10 bytes of row 25 contain control data relating to the received page as shown in Table 1. The remaining 14 bytes are free for use by the microcomputer. Fig.10 Organization of the extension memory.

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). DIP SOLDERING BY DIPPING OR BY WAVE The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds. The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. REPAIRING SOLDERED JOINTS Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 C, contact may be up to 5 seconds. QFP REFLOW SOLDERING Reflow soldering techniques are suitable for all QFP packages. The choice of heating method may be influenced by larger plastic QFP packages (44 leads, or more). If infrared or vapour phase heating is used and the large packages are not absolutely dry (less than 0.1% moisture content by weight), vaporization of the small amount of moisture in them can cause cracking of the plastic body. For more information, refer to the Drypack chapter in our "Quality Reference Handbook" (order code 9397 750 00192). March 1992 31
SAA5244A
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 from 50 to 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. Preheat for 45 minutes at 45 C. WAVE SOLDERING Wave soldering is not recommended for QFP 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 footprint must be at an angle of 45 to the board direction and must incorporate solder thieves downstream and at the side corners. Even with these conditions, do not consider wave soldering the following packages: QFP52 (SOT379-1), QFP100 (SOT317-1), QFP100 (SOT317-2), QFP100 (SOT382-1) or QFP160 (SOT322-1). 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.
