property rights. Use of the Macrovision anti-copy

process in the device is licensed for non-commercial

home use only. Reverse engineering or disassembly is

prohibited. Please contact your nearest Philips

Semiconductors sales office for more information.

2 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.
