Combining a fully integrated video processing feature set, 2D/3D graphics engine and ultra efficient VIA DDR memory controller, the VIA CLE266 Chipset is designed to enable high quality digital video streaming and digital video playback in a new generation of fanless, small form factor PCs and IA devices.
The VIA CLE266 chipset is the product of a new vision, blending the power of VIA DDR Chipset technology with the features required for a complete range of digital video functions. These include MPEG-2 decoding and video scaling for high quality digital video acceleration and an integrated 128-bit 2D and 64-bit 3D graphics engine with internal AGP 8X and Alpha Blending for multimedia and gaming applications. Supplied with 2.1GB per second of bandwidth from the ultra-fast DDR memory subsystem, the VIA CLE266 enables real world performance in key applications like video streaming or digital video playback that equals that of the most powerful PC systems in production today, while operating as part of a fanless power efficient, low cost device. In addition the CLE266 supports CRT, LCD or TV dual display technology, two Video Capture ports and Picture in Picture functionality for multi-channel capability.
The VIA CLE266 North Bridge is connected to the very latest in South Bridge technology, the VIA VT8235 through a 4X V-Link connection to the North Bridge transferring data at 266MB/s, twice the speed of the conventional PCI bus. This enables CLE266 based systems and devices to take advantage of the integrated support for 6 USB 2.0 ports with 40 times more bandwidth than USB 1.1, as well as ATA-133, the fastest available IDE interface. Additional features include integrated VIA MAC for 10/100Mbps Ethernet, integrated PCI support, 6 Channel Surround Sound AC-97 audio interface and MC-97 modem.
Benefits of VIA CLE266
A Leading Edge Digital Video Experience: The integrated VIA 2D/3D 128-bit graphics engine with internal AGP 8X possesses every feature required for digital video. Hardware MPEG-2 decoding delivers must have applications like digital video playback and and video streaming at an equivalent level to today’s multi-gigahertz, discrete graphics PC systems, at a fraction of the cost.
High Speed DDR Memory Subsystem: The integrated graphics engine and Socket-370 processor benefit from the 2.1GB/sec of bandwidth available from the DDR memory subsystem ensuring system performance is maximized across the whole spectrum of applications.
Designed for Fanless, Low Power Solutions: The CLE266 has been designed from the ground up to minimize power usage and heat dissipation. The low transistor count in the graphics core and low voltage DDR memory enable passive cooling solutions, while the CLE266 is fully compatible with the latest mobile power management specifications.
Market Leading South Bridge Technology: The VT8235 South Bridge possesses a complete suite of the very latest I/O and communication technologies including USB2.0 enabling peripheral connectivity 40 times faster than in previous generation systems and ATA-133, the fastest IDE interface currently available.
