(6 dots for each step)
Vertical starting position: 64 different positions
(4 scan-lines for each step)
8 foreground character colours: selection of only 2 out of
the 8 (outside the window) and 4 out of the of 8 (in the
window) in the same row
3 character shadowing modes:

GENERAL DESCRIPTION
The PCB8517 is a stand-alone OSD which is used to
display the adjustment/status information on the screen of
an auto-sync monitor for menu driving application.
The display operation of the device is controlled by a
microcontroller which programs the internal 273 bytes of
RAM via a 3-wire high-speed serial interface. The on-chip
PLL oscillator and programmable character height are
used to keep the same character size displayed on the
screen in different display modes, VGA, SVGA and XGA
for example.
The OSD of the PCB8517 provides display buffers of
10 rows with 24 characters each. These display buffers
can select from 128 customized character fonts (with
12
×
16 bit resolution) to be displayed. The characters
displayed on the screen can be specified double height,
double width, different colour and with/without shadowing.
Three positional background windows are provided for
multi-level application.
