The SAA7104E; SAA7105E is an advanced
next-generation video encoder which converts PC
graphics data at maximum 1280
(optionally 1920
NTSC (60 Hz) video signals. A programmable scaler and
anti-flicker filter (maximum 5 lines) 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.

DESCRIPTION
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 1280
resolution/60 Hz (PIXCLK < 85 MHz). Alternatively this
port can provide Y, P
The device includes a sync/clock generator and on-chip
DACs.
All inputs intended to interface to the host graphics
controller are designed for low-voltage signals between
down to 1.1 V and up to 3.6 V.
