2 channels of video data (10-bit each for RGB for each channel, totaling 60 bits) and control signals (HSYNC,
VSYNC, DE and two user-defined signals) along with clock signal. The dual high speed LVDS channels supports
single pixel in-single pixel out and dual pixel in-dual pixel out transmission modes. The FPD-Link chipset is
suitable for a variety of display applications including LCD Monitors, LCD TV, Digital TV, and DLP TV, and
Plasma Display Panels.
Using a true 10-bit color depth system, the 30-bit RGB color produces over 1.07 billion colors to represent High
Definition (HD) displays in their most natural color, surpassing the maximum 16.7 million colors achieved by 6/8-
bit color conventionally used for large-scale LCD televisions and LCD monitors.
LVDS TRANSMITTER
The LVDS Transmitter serializes LVCMOS/LVTTL RGB video data and control signal timing into LVDS data
streams.
SINGLE PIXEL AND DUAL PIXEL INTERFACE
The DS90C3201 LVDS ports support two modes: Single Pixel mode (30-bit LVDS output) and Dual Pixel mode
(2 x 30-bit LVDS output). For Single Pixel mode, the Odd LVDS ports for 10-bit RGB data are utilized. For the
Dual Pixel mode, both Odd and Even LVDS ports are utilized for 10-bit RGB data.
SELECTABLE INPUT DATA STROBE
The Transmitter input data edge strobe can be latched on the rising or falling edges of input clock signal. The
dedicated RFB pin is used to program input strobe select on the rising edge of TCLK IN or the falling edge of
TCLK IN.
2-WIRE SERIAL COMMUNICATION INTERFACE
Optional Two-wire serial interface programming allows fine tuning in development and production environments.
The Two-wire serial interface provides several capabilities to reduce EMI and to customize output timing. These
capabilities are selectable/programmable via Two-wire serial interface: Programmable LVDS Swing Control,
Adjustable Input Setup/Hold Control, Input/Output Channel Control.
PROGRAMMABLE LVDS SWING CONTROL
Programmable LVDS amplitude (V_OD) and LVDS offset voltage (V_OS) of the differential signals can be adjusted
for better impedance matching for noise and EMI reduction. The low level LVDS swing mode and offset voltage
can be controlled via Two-wire serial interface.
ADJUSTABLE INPUT SETUP/HOLD CONTROL
Programmable LVCMOS/LVTTL Data Input Setup and Hold Times can be adjusted with respect to TCLK IN for
convenient interface with a variety of graphic controllers and video processors. Feature is controlled via Two-wire
serial interface.
INPUT/OUTPUT CHANNEL CONTROL
Full independent control for input/output channels can be disabled to minimize power supply line noise and
overall power dissipation. Feature is configured via Two-wire serial interface.
