Functional Description
FPD-LINK RECEIVER
The LVDS based FPD-Link Receiver inputs video data and
control timing through 4-LVDS channels plus clock to provide
24-bit color or 3-LVDS channels can be used for 18-bit color.
The video data is converted to a parallel data stream and
routed to the 8-6 bit translator.
SPREAD SPECTRUM SUPPORT
The FPD-Link receiver supports graphics controllers with
Spread Spectrum interfaces for reducing EMI. The Spread
Spectrum methods supported are Center and Down Spread.
A maximum of 2% total is supported at a frequency modu-
lation of 100kHz maximum.
8-6 BIT TRANSLATOR
8-bit data is reduced to a 6-bit data path via a time multi-
plexed dithering technique or simple truncation of the LSBs.
This function is enabled via the input control pins.
DATAPATH BLOCK AND RSDS TRANSMITTER
6(8)-bit video data (RGB) is input to the Datapath Block
supports up to an 85 MHz pixel rate. The data is delayed to
align the Column Driver Start Pulse (STH) with the Column
Driver data. The data bus (RSR[2:0]P/N, RSG[2:0]P/N,
RSB[2:0]P/N) outputs at a 170 MHz rate on 9 differential
output channels. The clock is output on the RSCKP/N differ-
ential pair. The RSDS Column Drivers latch data on both
positive and negative edges of the clock. The RSDS output

TIMING CONTROL FUNCTION
The Timing Control function generates control to Column
Drivers, Row Drivers, and power supply. The GPOs (General
Purpose Outputs) provide for CD latch pulse, REV, and Row
Driver control generation. The General Purpose Outputs
allow the user to generate control anywhere within the frame
data. Standard Row Driver interface or Custom Row Driver
interfaces can be implemented with the GPOs (General
Purpose Outputs).
RSDS OUTPUT VOLTAGE CONTROL
The RSDS output voltage swing is controlled through an
external load resistor connected to the R
pin. The RSDS
output signal levels can be adjusted to suit the particular
application. This is dependent on overall LCD module design
characteristics such as trace impedance, termination, etc.
The RSDS output voltage is inversely related to the R
PI
value. Lower R
values will increase the RSDS output volt-
age swing and consequently overall power consumption will
also increase.
