LVDS Interface

The LVDS interface is dedicated and independent of the other video interfaces and provides the following features:.

•Supports ANSI/TIA/EIA-644-2001 specification compliance

•Supports 25 to 112 MHz single/dual channel LVDS interface with Spread Spectrum Clocking (SSC)

NOTE	Spread Spectrum Clocking is controlled in BIOS Setup under the
	Advanced menu. Refer to Chapter 4, BIOS Setup for the Clock
	Configuration where you can set the Spread Spectrum Clock.

•Supports maximum TFT pixel format of 1x18 bpp for one channel and 2x18 bpp for 2 channels

•Supports flat panel size up to UXGA (1600 x 1200)

•Supports Wide panel size up to WUXGA (1920 x 1200)

•Provides Automatic Panel Detection using EPI (Embedded Panel Interface based on VESA EDID™ 1.3)

•Supports Intel® Display Power Savings Technology 2.0

Refer to Table 3-21 for the Simplified LVDS Interface Pin/Signal Descriptions.
