The FPD87352CXA is timing controller that combines an LQFP package with body size mm mm LVDS single pixel input interface with National’s Reduced 1.4 mm, 0.5 mm pitch Swing Differential Signaling (RSDS) output column driver interface for XGA/WXGA/HDTV I,II,- resolutions. It resides on the Flat Panel Display and provides the data buffering and control signal generation. FPD-Link, lower dynamic power, low EMI (Electro Magnetic Interference) interface is used between this timing controller and the host system. RSDS interface is used between the timing controller and the column drivers. The dual 13/10 pair differential bus conveys up to 24-bit color data for XGA, WXGA and HDTV panels.
