The SAA7113H 9-bit video input processor features four analog inputs, internal analog source selectors, automatic switching, automatic frequency tracking, automatic white balance, and automatic gamma correction.
The SAA7113H is a 9‑bit video input processor that integrates two analog preprocessing channels, programmable gain control, on‑chip clock generation and a multi‑standard VBI data slicer. It supports a wide range of video standards (PAL, NTSC, SECAM) and provides digital video output via an I²C‑controlled VPO bus.
The document includes functional descriptions, block diagrams, pin configurations, electrical characteristics, timing diagrams and ordering information. It also lists typical applications such as notebook graphics, PCMCIA cards, AGP graphics cards, image processing, video phones and security systems.
