13.10.1.General definition
The SDA55XX is a single chip teletext decoder for decoding World System Teletext data as well as
Video Programming System (VPS), Program Delivery Control (PDC), and Wide Screen Signalling
(WSS) data used for PAL plus transmissions (Line 23). The device also supports Closed caption
acquisition and decoding. The device provides an integrated general-purpose, fully 8051-compatible
Microcontroller with television specific hardware features. Microcontroller has been enhanced to provide
powerful features such as memory banking, data pointers, and additional interrupts etc. The on-chip
display unit for displaying Level 1.5 teletext data can also be used for customer defined on screen
displays. Internal XRAM consists of up to 16 Kbytes. Device has an internal ROM of up to 128 KBytes.
ROMless versions can access up to 1 MByte of external RAM and ROM. The SDA 55XX supports a
wide range of standards including PAL, NTSC and contains a digital slicer for VPS, WSS, PDC, TTX
and Closed Caption, an accelerating acquisition hardware module, a display generator for Level 1.5
TTX data and powerful On screen Display capabilities based on parallel attributes, and Pixel oriented
characters (DRCS).
