DESCRIPTION

The STV5348 decoder is a computer-controlled

teletext device including an 8 page internal mem-

ory. Data slicing and capturing extracts the teletext

information embedded in the composite video sig-

nal. Control is accomplished via a two wire serial

I

2C bus ®. Chip address is 22h. Internal ROM pro-

vides a character set suitable to display text using

up to seven national languages. Hardware and

software features allow selectable master/slave

synchronization configurations. The STV5348 also

supports facilities for reception and display of cur-

rent level protocol data.
