Function Description
FPD-LINK RECEIVER
The LVDS based FPD-Link Receiver receives input video
data and control timing. Four LVDS channels plus clock
provide 24-bit color.
RESETN initializes the chip with the default register values
for the LUT values from internal ROM or external EEPROM.
SSC (SPREAD SPECTRUM CONTROL)
This SSC function provides a means for reducing EMI. This
feature uses external SSC signal source that provides syn-
chronized spread spectrum for RSDS and control signal
outputs.
2-WIRE SERIAL EEPROM INTERFACE
The Serial EEPROM Interface controls the FPD87352CXA
initialization of LUT register. If the EEPROM is not present,
the
LUT
value
is

ROM
of
CLK & DATA SYNCHRONIZER
This function delays and aligns data to match the internal
data process which included RSDS skew control by
RSKEW[2:0]. All the data processes are needed to be
aligned each data path through RSDS output and LCD tim-
ing control signal.
LUT REGISTER
This block provides the RTC reference values to be pro-
cessed on the RTC Data Processor Block. The setting of
RTC reference values is provided by the external EEPROM
in normal condition. If the external EEPROM is not present it
will use the internal ROM’s RTC reference values. The RTC
reference values are the new gray values depending on the
difference between the current frames’ RGB gray data and
the previous frame’s RGB gray data of same pixel.
RTC DATA PROCESSOR
This function generates new gray values depending on the
difference of the current RGB gray data and same pixel of
the previous frame. The reference values fetch from the LUT
(Look Up Table) values in the LUT Register.
RSDS INTERFACE WITH SKEW CONTROL
This functional block transforms CMOS level signal to RSDS
for the system clock (DCLK) and RGB color data. The RSDS
skew is controlled by RSKEW[2:0] with delay steps between
the RSF/BCKP/N and RSF/BR/G/B[3:0]P/N which is imple-
mented in CLK & Data synchronizer.
