Overview

The CL-GD5480 is a high-performance, cost-effective VisualMedia solution that combines graphics, animation, better-than-TV quality full-screen video, and software 3D acceleration in an integrated single-chip device. The chip is part of the Cirrus Logic Alpine family and interfaces with high-speed SGRAM frame buffer.

Key Features:

64-bit high-bandwidth synchronous DRAM interface with 800 Mbytes/sec. peak memory bandwidth
Microsoft PC97-compliant
Video conferencing advantages
- Glueless digital camera interface with direct support of CCIR 6:5:6 format
- Dual-hardware video window for local and remote viewing
- Optional PCI bus master conversion to YUV 4:2:0 for off-loading CPU during local view transmission
- Remote and local view mirror image and vertical flip options
- Continuous XY filtered downscaling for video conference display size
Intel Intercast support
- Luminance-only video capture mode for efficient VBI data processing
- Simultaneous capture and transfer of VBI data to system memory while TV picture is displayed in the video window
- PCI bus master write operation for fast transfer of VBI data to system memory without CPU intervention
MPEG playback assist for native MPEG format of planar YUV 4:2:0, freeing CPU of conversion burden
3 x 8 palette LUT with independent RGB addressing for color adjustment (such as gamma correction) in 15-, 16-, and 24-bpp modes
Packaged in a 208-pin PQFP with industry-standard V-Port for interfacing directly to various video input devices
GPIO, I2C bus interfaces, and V-Port for glueless connection to external devices
Compatible with the Cirrus Logic Alpine family, featuring stable software drivers, extensive software QA process, and best language localization support
VPM (video port manager) interface for easy peripheral application software development
