FPD87392BXB
+3.3V TFT-LCD Timing Controller with Dual LVDS
Inputs/Dual RSDS^™ Outputs for TFT-LCD Monitor and
Notebook (SXGA/SXGA+/UXGA)
General Description
The FPD87392BXB Panel Timing Controller is an integrated
FPD-Link + RSDS™ + TFT-LCD Timing Controller. The logic
architecture is implemented using standard and default tim-
ing controller functionality based on an Embedded Gate
Array. The device is reconfigurable to the needs of a specific
application by providing user-defined specifications or cus-
tomer supplied VHDL/Verilog code.
The FPD87392BXB is a timing controller that combines an
LVDS dual pixel input interface with National’s Reduced
Swing Differential Signaling (RSDS™) output column driver
interface for SXGA, SXGA+ and UXGA resolutions. It re-
sides on the TFT-LCD panel and provides the data buffering
and control signal generation. The RSDS™ data path to the
column driver contributes toward lowering radiated EMI and
reduced system dynamic power consumption. The RSDS™
dual 12 pair differential bus conveys up to 24-bit color data
for SXGA/SXGA+/UXGA panels when using VESA 60Hz
standard timing.
