FPD87310
Universal Interface XGA Panel Timing Controller with
RSDS^™ (Reduced Swing Differential Signaling) and
FPD-Link
General Description
The FPD87310 Panel Timing Controller is an integrated
FPD-Link + RSDS + TFT-LCD Timing Controller. It resides
on the Flat Panel Display and provides the interface signal
routing and Timing Control between Graphics or Video Con-
trollers and a TFT-LCD system. FPD-Link, a low power, low
EMI (ElectroMagnetic Interference) interface is used be-
tween this Controller and the Host system.
A RSDS (Reduced Swing Differential Signaling) Column
Driver interface is used between the Timing Controller and
the Column Drivers.
Programmable, General Purpose Outputs provide Row and
Column Driver control. The FPD87310 is configured via
metal mask initialization value or an optional external serial
EEPROM. Reserved space in the EEPROM is available for
display identification information. The system can access the
EEPROM to read the display identification data or program
initialization values used by the FPD87310.
This single 9-bit+CLK differential bus conveys the 18 bits
color data for XGA panels at 130 Mb/s when using VESA 60
Hz standard timing.
