com ADVANCED INFORMATION NOV, 1997 LMC7532 Low EMI, Low Power XGA/SVGA TFT-LCD Column Driver General description The LMC7532 is a Column Driver suitable for National’s Reduced Swing Differential Signalling (RSDS) digital interface.
It converts this 18-bit digital data into analog voltage for 300 or 309 columns, charging each sub-pixel to the correct gray level corresponding to the digital value.
The RSDS path to the panel timing controller contributes toward lowering radiated EMI, reducing system power consumption and eliminates one of the two pixel busses used in typical XGA TFT-LCD panels today.
This single 9-bit differential bus conveys the 18-bit color data for XGA panel...
