National Semiconductor Introduces TFT-LCD Timing Controllers with RSDS Outputs For VGA/SVGA, XGA and Wide XGA Resolutions

Feb 8, 2005

February 8, 2005 - National Semiconductor Corporation (NYSE:NSM) today introduced the FPD87370 and FPD87346, timing controllers that combine an LVDS single-pixel input interface with National's RSDS™ (Reduced Swing Differential Signaling) output driver interface for VGA/SVGA, XGA and Wide XGA resolutions. The timing controllers reside on the TFT-LCD panel and provide the data buffering and control-signal generation for VGA/SVGA, XGA, and Wide XGA graphic modes. The RSDS™ path to the column driver contributes toward reducing the bus width from the timing controller, lowering the radiated electromagnetic interference (EMI) and reducing system dynamic power consumption.

The single RSDS bus conveys the 8-bit color data for VGA/SVGA, XGA, and Wide XGA panels at 170 Mb/s when using VESA 60 Hz standard timing.

Key Features for the FPD87370 and FPD87346:

  • 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 (FPD87370), SVGA (FPD87346), 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

Pricing and Availability
National’s FPD87370 and FPD87346 are available now in 64-pin TQFP packages.  The FPD87370 costs $5.00 and the FPD87346 costs $3.00 in 1,000-unit quantities.
