UPD160083

PRELIMINARY PRODUCT INFORMATION MOS INTEGRATED CIRCUIT www.DataSheet4U.com µPD160083 480-OUTPUT TFT-LCD SOURCE DRIVER (COMPATIBLE WITH 256-GRAY SCALES) DESCRIPTION The µ PD160083 is a source driver for TFT-LCDs capable of dealing with displays with 256-gray scales. Data input is based on digital input configured as 8 bits by 3 dots (1 pixel) with double clock edge, which can realize a full-color display of 16,777,216 colors by output of 256 values γ -corrected by an internal D/A converter and 9-by-2 external power modules. Because the output dynamic range is as large as VSS2 + 0.1 V to VDD2 – 0.1 V, level inversion operation of the LCD’s common electrode is rendered unnecessary. Also, to be able to deal with dot-line inversion, n-line inversion and column line inversion when mounted on a single side, this source driver is equipped with a builtin 8-bit D/A converter circuit whose odd output pins and even output pins respectively output gray scale voltages of differing polarity. Assuring a clock frequency of 85 MHz when driving at 3.0 V, this driver is applicable to UXGAstandard (1600 1200), SXGA-standard (1280 1024) TFT-LCD panels. FEATURES RSDSTM (Reduced Swing Differential Signaling) interface 480 outputs Input of 8 bits (gradation data) by 3 dots with double clock edge sampling Capable of outputting 256 values by means of 9-by-2 external power modules (18 units) and a D/A converter Logic power supply voltage (VDD1): 2.7 to 3.6 V Driver power supply voltage (...
