ASTLC5002A - 6-BIT RSDS 384 CHANNELS TFT-LCD SOURCE DRIVER

The ASTLC5002A is a TFT LCD source driver having a Reduced Swing Differential Signaling (RSDS) digital interface. It converts 3x6-bit digital data into analog voltages for 384 output channels, hence delivering to each sub-pixel the accurate gray level corresponding to the input digital value.

The RSDS path to the panel timing controller contributes towards lowering radiated EMI, reducing system power consumption and eliminates one of the two pixel busses used in typical XGA, SXGA TFT LCD panels. This single 9-pair differential data bus conveys the 3x6-bit color data for XGA and SXGA panels.
