The SAA7102; SAA7103 is used to encode PC graphics
data at maximum 800
NTSC (60 Hz) video signals. A programmable scaler and
interlacer ensures properly sized and flicker-free TV
display as CVBS or S-video output.
Alternatively, the three Digital-to-Analog Converters
(DACs) can output RGB signals together with a TTL
composite sync to feed SCART connectors.
When the scaler/interlacer is bypassed, a second VGA
monitor can be connected to the RGB outputs and
separate H and V-syncs as well, thereby serving as an
auxiliary monitor at maximum 800
(PIXCLK < 45 MHz).
The device includes a sync/clock generator and on-chip
DACs.
