CS5841

Century Semiconductor Inc. om GENERAL DESCRIPTION w w CS5841 is a TFT-LCD timing controller, which is applicable to 6-bit data XGA (1024*768), SXGA (1280*1024) and SVGA (800*600). CS5841 can update the response timing for display mode of XGA, SXGA and SVGA automatically. CS5841 provides a selectable polarity check function to inverse output data for EMI reducing, w .D a S a t e e h U 4 t .c CS5841 LCD Panel Timing Controller (14") FEATURES (continued) 1. can vary the pulse width & starting position of LP signal and POL signal polarity position changed along with LP signal 2. can vary the pulse width & starting position of CLKV signal and CLKVW time Control ASIC output timing design is based on Data Enable signals Resolution Auto detect for SVGA, XGA and SXGA Embedded Power On Reset circuits, Vth=2.1V, tolerance ± 0.3V ESD spec. 4KV Power On Latch Up 200mA/7.5V Single 3.3V supply 100-pin TQFP package (same as M65476BFP) BLOCK DIAGRAM DENA VD HD DCLKI INVI PNDCLK PNHVD PNCLKH PNINV ICMD1 ICMD0 SVMD VXMD PL HOL w .D INPUT SELECTOR DATA-PATH SAMPLE POWER ON RESET t a S a QD e h t e POL GENERATOR LP GENERATOR POLARITY Interface (5V/3.3V[CMOS] input, 3.3V[CMOS] output) 6-bit data single-port input, dual-port output.
