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,  
CB), VBS (GREEN, CVBS) and C (RED, CR) (signals in parenthesis are optional); all at  
10-bit resolution  
Non-Interlaced (NI) CB-Y-CR or RGB input at maximum 4 : 4 : 4 sampling  
Downscaling from 1 : 1 to 1 : 2 and up to 20 % upscaling  
Optional interlaced CB-Y-CR input 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
