ASTLC5101A - 8-BIT RSDS 480 CHANNELS TFT-LCD SOURCE DRIVER
GENERAL DESCRIPTION
This IC is a 480-output TFT-LCD source driver with an RSDS (Reduced Swing Differential Signaling) interface for UXGA and SXGA panels that use a single 12-bit differential bus to convey 24-bit data. The RSDS interface allows to reduce EMI. It receives 12-bit differential data from timing controller and outputs 480-channel LCD driving voltage. 18 external reference voltages are available for the Gamma correction.
