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.

2. Features

■ Digital PAL/NTSC encoder with integrated high quality scaler and anti-ﬂicker ﬁlter for

TV output from a PC

■ 27 MHz crystal-stable subcarrier generation

■ Maximum graphics pixel clock 45 MHz at double edged clocking, synthesized on-chip

or from external source

■ Up to 800 × 600 graphics data at 60 Hz or 50 Hz with programmable underscan range.

■ Three Digital-to-Analog Converters (DACs) at 27 MHz sample rate for CVBS (BLUE,

C_B), VBS (GREEN, CVBS) and C (RED, C_R) (signals in parenthesis are optional); all at

10-bit resolution

■ Non-Interlaced (NI) C_B-Y-C_Ror RGB input at maximum 4 : 4 : 4 sampling

■ Downscaling from 1 : 1 to 1 : 2 and up to 20 % upscaling

■ Optional interlaced C_B-Y-C_Rinput of Digital Versatile Disc (DVD) signals

■ Optional non-interlaced RGB output to drive second VGA monitor (bypass mode with

maximum 45 MHz)

■ 3 × 256 bytes RGB Look-Up Table (LUT)

■ Support for hardware cursor

■ Programmable border color of underscan area

■ On-chip 27 MHz crystal oscillator (3rd-harmonic or fundamental 27 MHz crystal)

■ Fast I²C-bus control port (400 kHz)

■ Encoder can be master or slave

■ Programmable horizontal and vertical input synchronization phase

■ Programmable horizontal sync output phase

■ Internal Color Bar Generator (CBG)

■ Optional support of various Vertical Blanking Interval (VBI) data insertion
