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