FPD87370 FPD87370AXA Low EMI, Low Dynamic Power VGA/XGA/WXGA TFT-LCD Timing Controllerwith Reduced Swing Differential Signaling (RSDS) Outputs Literature Number: SNOSAG4A FPD87370AXA Low EMI, Low Dynamic Power VGA/XGA/WXGA TFT-LCD Timing Controller with Reduced Swing Differential Signaling (RSDS™) Outputs General Description Features The FPD87370AXA is a timing controller that combines an LVDS single pixel input interface with National's Reduced Swing Differential Signaling (RSDS™) output driver interface for VGA, XGA and Wide XGA resolutions. It resides on the TFT-LCD panel and provides the data buffering and control signal generation for VGA, XGA, and Wide XGA graphic modes. The RSDS™ path to the column driver contributes toward lowering radiated EMI and reducing system dynamic power consumption. This single RSDS™ bus conveys the 8-bit color data for VGA, XGA, and Wide XGA panels at 170 Mb/s when using VESA 60 Hz standard timing. ■ Reduced Swing Differential Signalling (RSDS™) digital ■ ■ ■ ■ ■ ■ ■ ■ bus reduces dynamic power, EMI and bus width from the timing controller LVDS single pixel input interface system Input clock range from 25 MHz to 85 MHz Drives RSDS™ Column Drivers at 170 Mb/s with an 85 MHz clock (Max.) Virtual 8 bit color depth in FRC/Dithering mode Single narrow 9-bit differential Source Driver bus minimizes width of Source PCB Ability to drive VGA, XGA and Wide XGA TFT-LCD Systems Failure detect function in DE mode (Bonding Option) CMOS circuitry operates from a 3.0V–3.6V supply System Diagram 20116501 FIGURE 1.
