SAA7102; SAA7103
Digital video encoder
Rev. 04 — 18 January 2006
Product data sheet
1. General description
The SAA7102; SAA7103 is used to encode PC graphics data at maximum 800
×
600
resolution to PAL (50 Hz) or 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
×
600 resolution/60 Hz (PIXCLK < 45 MHz).
The device includes a sync/clock generator and on-chip DACs.
