Chapter 1 <Introduction>
1.1 <Product Overview>
LV-66A is the Mini-ITX motherboard based on VIA chipset. It integrates VIA embedded
chipset for CN896 with VT8251, two DDR2 400/533/667 SDRAM 64-bit single channel, and
serial ATA II supporting 1.5 Gbit/s and 3 Gbit/s transfer rate with RAID 0/1/0+1/5 and JBOD
array Technology supported to provide the economical embedded platform.
VIA CN896 & VT8251 Chipset
The board comes with the VIA embedded chipset of CN896, supports two DDR2
400/533/667 SDRAM, Chrome9™ HC Integrated Graphics with 2D / 3D / Video Controllers,
The VT8251 provides the board to support Ultra V-Link interface with 1 GB/sec maximum
bandwidth, four serial ATA II ports with RAID array function, 8 x USB2.0 ports and 7.1
channels HD audio.
Multimedia solution
Based on VIA CN896 chipset, the board provides single/dual 18/24-bit LVDS or DVI
interface, which supports dual independent display with CRT.
Onboard HD codec provides the high quality of sound including 7.1-channel stereo DACs.
Two LAN Interface
LV-66A also comes with two Giga LAN interface, support boot-on-LAN and wake-on-LAN
function.
High Speed Hot-plug Interface
Based on VIA VT8251 the board provides 8 USB2.0 interfaces with up to 480Mbps of
transferring rate.
