SAA7104E Key Features
- Digital PAL/NTSC encoder with integrated high quality scaler and anti-flicker filter for TV output from a PC
- Supports Intel® Digital Video Out (DVO) low voltage interfacing to graphics controller
- 27 MHz crystal-stable subcarrier generation
- Maximum graphics pixel clock 85 MHz at double edged clocking, synthesized on-chip or from external source
- Programmable assignment of clock edge to bytes (in double edged mode)
- Synthesizable pixel clock (PIXCLK) with minimized output jitter, can be used as reference clock for the VGC, as well)
- PIXCLK output and bi-phase PIXCLK input (VGC clock loop-through possible)
- Hot-plug detection through dedicated interrupt pin
- Supported VGA resolutions for PAL or NTSC legacy video output up to 1280 × 1024 graphics data at 60 or 50 Hz frame rate
- Supported VGA resolutions for HDTV output up to 1920 × 1080 interlaced graphics data at 60 or 50 Hz frame rate
