(EBU PDC System A)
• Acquisition and decoding of Teletext packet 8/30/2 data
(EBU PDC System B)
• Separate storage of VPS data and packet 8/30/2
allowing dual standard PDC decoders
• I2C-bus interface with automatic word address
increment
• Programmable interrupt for data received
• Programmable error level detection
• Single +5 V power supply.
GENERAL DESCRIPTION
The SAA5233 is a dual standard Program Delivery Control
(PDC) decoder, allowing the reception and decoding of
both VPS data (EBU PDC System A) and Teletext packet
8/30/2 data (EBU PDC System B). It is intended for use in
European video recorders which are manually
programmed, so that they receive broadcast real time
switching signals for accurate timing of program recording.
