• Single or dual LVDS Transmitter each working as Single/Dual LVDS Transmitter up to 165Mpixels/s
• Panel fitting scalar-up scale to 1600x1200
• Panel resolution up to 1920x1200 (@60Hz Frame Rate
• The ADD2-LVDS-Dual supported by KT965 Family
• The ADD2-LVDS-Single supported by KT965 and 986LCD-M Families
• LVDS low jitter PLL accepts spread spectrum input
• LVDS 18-bit and 24-bit output
• 2D dither engine
• Panel protection and power sequencing
• High-speed SDVO1 serial (1G~2Gbps) AC-coupled
• differential RGB inputs
• Low voltage interface support to graphics device
• Programmable power management
• Fully programmable through serial port
• Configuration through opcodes1
• Complete Windows and DOS driver support
• 3.3/5V LCDVCC selection
• Backlight Signal inversion selection
The ADD2-LVDS cards are based on the Chrontel CH7308A LVDS transmitter. The ADD2-LVDS-Dual is
equipped with two CH7308A and supports two independent displays having resolutions up to 1600x1200
(1920x1200 possible). The ADD2-LVDS-Single only has one CH7308A. The cards are designed for the PCIExpressx16 connector which on the 986LCD-M family of motherboards and on the KT965/Flex motherboard
is multiplexed PCI-Expressx16 and SDVO. When the ADD2-LVDS card is plugged into the PCI-Expressx16
connector then the motherboard automatically detects the card and select SDVO output. The card operates
at pixel rates of up to 165MHz per link, supporting 1920x1200 panels at a 60Hz refresh rate. The LVDS
transmitter includes a panel fitting up-scaler and a programmable dither function to support 18-bit LCD
panels. Data is encoded into commonly used formats, including those specified in the OpenLDI and the
SPWG specifications.

For KT965 motherboard in single - or dual LVDS display configuration.
The display connected to the J1 LVDS port can be activated from BIOS by selecting the [CRT+LFP] or [LFP]
and the display connected to the J2 LVDS card can not be activated from BIOS, only via Intel Graphics
Media Accelerator Driver. The driver for the display connected to J1 can be selected in BIOS. The driver for
the display connected to J2 can not be selected; it will use the same display driver as selected for the J1
connection.
In BIOS select:
Chipset > NorthBridge Chipset Configuration > Video Function Configuration >
Boot Type = [CRT+LFP] or [LFP] or [CRT]
SDVO = [select display type no.]
By selecting Secure CMOS (or OEM Failsafe) it is possible to prevent Windows from changing the BIOS
“Boot Type” setting. For Windows use the Intel Graphics Media Driver version 6.14.10.4859
(win2K_xp1431.exe) or newer. Clone mode is not supported in dual LVDS application.
For 986LCD-M motherboard in dual LVDS display configuration.
(For single LVDS display application use onboard LVDS port, no ADD2-LVDS card is required).
The display connected to the onboard LVDS port (the display 1 type) can be activated from BIOS by
selecting the [CRT+LFP] or [LFP] and the display connected to the ADD2-LVDS card (the display 2 type) can
not be activated from BIOS, only via Intel Graphics Media Accelerator Driver.
In BIOS select:
Chipset > NorthBridge Chipset Configuration > Video Function Configuration >
Boot Type = [CRT+LFP] or [LFP] or [CRT]
Backlight Signal Inversion = [Disabled] or [Enabled]
LCDVCC Voltage = [3.3V] or [5V]
LVDS = [select display 1 (LFP) type no.]
SDVO = [select display 2 type no.]
By selecting Secure CMOS (or OEM Failsafe) it is possible to prevent Windows from changing the BIOS
“Boot Type” setting. For Windows use the Intel Graphics Media Driver version 6.14.10.4859

Appendix: How to remove LVDS connector
Removing the LVDS Cable/Connector used in different types of LVDS Cable Kits like 821517, can easily
damage the LVDS connector if it’s not done carefully, like just pulling the cable.
The best way to remove the connector is to pull the cable, but with only light force and at the same time
move the cable from side to side, meaning from 45º to 90º position compared to normally 0º. See pictures
below.
LVDS Connector to be removed
(Normal position of LVDS cable)
0º
PCB
(Pull only with light force)
90º
Two fingers
(10 - 20 movements)
45º
~2cm
Hold the cable by 2 fingers in a position something like 2 cm from the connector and start moving the cable
as described above. After something like 10-20 movements the connector will normally be released. When
the connector starts to gets loose be extra careful.
By this method the LVDS Cable/Connector can be disconnected hundred of times without being damaged.

The CON1 on the 821521 is based on JAE FI-X30H display connector. As an option it is possible to replace
the FI-X30H housing with a FI-E30H housing (using same terminals) and then add support for more displays.
By manually moving the CON1 terminals it is posible to support many different displays.
