Integrated VIP and Teletext (IVT1.0)
Product specification
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
• Digital data slicer and display clock phase-locked loop
reduce peripheral components to a minimum
• 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.
DESCRIPTION
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.
