Product specification
SAA5231
GENERAL DESCRIPTION
The SAA5231 is a bipolar integrated circuit intended as a successor to the SAA5030. It extracts Teletext Data from the
video signal, regenerates Teletext Clock and synchronizes the text display to the television syncs. The integrated circuit
is intended to work in conjunction with CCT (Computer Controlled Teletext), EUROM or other compatible devices.
Features
• Adaptive data slicer
• Data clock regenerator
• Adaptive sync separator, horizontal phase detector and 6 MHz VCO forming display phase locked loop (PLL)
