GENERAL DESCRIPTION The SAA7134HL is a single chip solution to digitize and decode video and sound, and to capture both data streams through the PCI-bus. FEATURES PCI and DMA bus mastering • PCI 2.2 compliant including full Advanced Configuration and Power Interface (ACPI) • System vendor ID, etc. via EEPROM • Hardware support for virtual addressing by MMU • DMA bus master write for video, audio, VBI and TS • Configurable PCI FIFOs, graceful overflow • Packed and planar video formats, overlay clipping. TV video decoder and video scaling • All-standards TV decoder: NTSC, PAL and SECAM • Five analog video inputs: CVBS and S-video • Video digitizing by two 9-bit ADCs at 27 MHz • Sampling according ITU-R BT.601 with 720 pixels/line • Adaptive comb filter for NTSC and PAL, also operating for non-standard signals • Automatic TV standard detection • Three level Macrovision copy protection detection according to Macrovision Detect specification Revision 1 • Control of brightness, contrast, saturation and hue • Versatile filter bandwidth selection • Horizontal and vertical downscaling or zoom • Adaptive anti-alias filtering • Capture of raw VBI samples • Two alternating settings for active video scaling • Output in YUV and RGB • Gamma compensation, black stretching. TV sound decoder and audio I/O • TV stereo decoding for NICAM and dual FM • Audio sampling locked to video field rate, no drift of audio stream against video stream • On-chip stereo audio ADCs and DACs (2 × 16-bit) • Sampling rate, e.g. 32, 44.1 and 48 kHz • Integrated analog audio pass-through for analog audio loop back cable to sound card. Peripheral interface • I2C-bus master interface: 3.3 and 5 V • Digital video output: ITU and VIP formats • TS input: serial or parallel • General purpose I/O, e.g. for strapping and interrupt • Propagate reset and ACPI state D3-hot. General • Package: LQFP128 • Power supply: 3.3 V only • Power consumption of typical application: 1 W • Power-down state (D3-hot): <20 mW • All interface signals 5 V tolerant • Reference designs available • SDK for Windows (95, 98, NT, 2000 and XP), Video for Windows (VfW) and Windows Driver Model (WDM).
