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
I2C 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.
