ZR36057 DATA SHEET www.DataSheet4U.com ENHANCED PCI BUS MULTIMEDIA CONTROLLER FEATURES T T T T T T T T Glueless interface to PCI bus (PCI spec. 2.1 compliant). Minimum interface to JPEG decoders (e.g. ZR36050 & ZR36016), MPEG1 decoders (e.g., ZR36110), video digitizers (e.g., SAA7110, SAA7111) and video encoders (e.g., SAA7188, MD207). Bi-directional DMA transfer of compressed data up to 11M bytes/sec. DMA transfer of video and overlay information. Support for fast still image compression and decompression. Smooth image down-scaler (up to 5-tap horizontal filter). On-chip pixel accurate masking. YUV-to-RGB converter with quantization noise reduction by error diffusion. T T T T T T T T T Video output: 15- and 16-bit RGB pixel formats, as well as 24-bit (packed and unpacked), and YUV 4:2:2. Hardware support for non-contiguous JPEG code buffers. Graceful recovery from extreme bus latencies both on video and code transfers. Choice of emulated interlaced video display, or single field display, to eliminate motion artifacts. Hardware support for simple, cost effective frame grabbing. I2C bus master port. Plug & Play support. 208-pin PQFP package. Accompanying software includes Video For Windows (VFW) drivers for Windows 3.1 and Windows 95. APPLICATIONS T T High quality video and audio capture/playback and editing boards for PCI systems.
