SAA5246A
FEATURES
• Complete Teletext decoder in a 48-pin DIL or 64-pin
QFP, integrated circuit
• Single +5 V power supply
• Both video and scan related synchronization modes are
supported
• RGB interface to standard colour decoder ICs, push-pull
output drive
DESCRIPTION
• Digital data slicer and display clock phase-locked loop
reduce peripheral components to a minimum
The SAA5246A is a single-chip teletext decoder IC for
decoding 625 line base World System Teletext
transmissions. The teletext decoder hardware is based on
the Enhanced Computer Controlled ECCT device
(SAA5243) with some additional features.
The Video Input Processor section of the device uses
mixed analog and digital designs in the data slicer and
clock phase-locked-loop functions. As a result the number
of external components are greatly reduced and no critical
or adjustable components are required.
• Data capture performance similar to SAA5231 (VIP2)
• Option for up to seven national languages
• Optional storage of packet 24 in the display memory
• Separate text and video signal quality detectors,
625/525 video status and language version all readable
via I2C-bus
• Automatic ODD/EVEN output control with override
• Control of display PLL free-run and rolling header via
I2C-bus
• VCS to SCS mode for stable 525 line status display.

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. Can be pulled higher by external pull-up resistor, (maximum leakage current ≈ 200 µA).

SAA5246A page memory organization
The organization of the page memory is illustrated by Fig.10. The SAA5246A provides an additional row as compared
with first generation decoders; this brings the display format up to 40 characters by 25 rows. Rows 0 to 23 form the
teletext page; row 24 is the extra row available for software generated status messages and FLOF/FASTEXT prompt
information.

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 SAA5246A 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 microprocessor.

Notes to Table 2
1. ‘−’ indicates a bit which does not exist and must be written to logic 0 for future compatibility.
2. All bits in registers R0 to R10 are cleared to logic 0 on power-up except bits D0 and D1 of registers R1, R5 and R6
which are set to logic 1.
3. All memory is cleared to ‘space’ (00100000) on power-up, except Row 0 Column 7 Chapter 0, which is ‘alpha’ white
(00000111) as the acquisition circuit is enabled but the page is on hold.
4. TB must be set to logic 0 for normal operation.
5. The I2C-bus slave address is 0010001.

1. Abbreviations are as for Table 1 except for DO CARE bits.
2. When the DO CARE bit is set to logic 1 this means the corresponding digit is to be taken into account for page
request. If the DO CARE bit is set to logic 0 the digit is ignored. This allows, for example, ‘normal’ or ‘timed page’
selection.
3. If HOLD is set LOW, the page is held and not updated

Character sets
The WST specification allows the selection of national character sets via the page header transmission bits, C12 to C14.
The basic 96 character sets differ only in 13 national option characters as indicated in Tables 15 - 23 with reference to
their table position in the basic character matrix illustrated in Table 14. The SAA5246A automatically decodes
transmission bits C12 to C14. Tables 6 - 13 illustrate the character matrices.
Character bytes are listed as transmitted from b1 to b7.

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.
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.
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.
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).
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.
SDIP
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.
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 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.
• 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).
REPAIRING SOLDERED JOINTS
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.
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
A mildly-activated flux will eliminate the need for removal
of corrosive residues in most applications.
Reflow soldering techniques are suitable for all QFP
packages.
REPAIRING SOLDERED JOINTS
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).
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.
