CS5842

Century Semiconductor Inc. om GENERAL DESCRIPTION w w CS5842 is a TFT-LCD timing controller, which is applicable to 8-bit data XGA (1024*768), SXGA (1280*1024). CS5842 can update the response timing for display mode of XGA and SXGA automatically. CS5842 provides a selectable polarity check function to inverse output data for EMI reducing, when the toggle number of ODD/EVEN RGB outputs is larger than 13. w .D a S a t e e h U 4 t .c CS5842 LCD Panel Timing Controller (15") FEATURES (continued) Correspondent to control timing & specific resolution for different Driver IC by changing a Mask: 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 tgs time Control ASIC output timing design is based on Data Enable signals Embedded Power On Reset circuits, Vth=2.1V, tolerance ± 0.3V ESD spec. 4KV Power On Latch Up 200mA/6.6V Single 3.3V supply 144-pin LQFP package BLOCK DIAGRAM DENA VD HD DCLK1 INV PNDCLK PNVD PNHD POLIN ICMD(2~1) DATAHT SXMD HOL P POWER ON RESET LQD S a e h t e STH1/STH8 GENERATOR POL/SHC GENERATOR STV1/STV3 GENERATOR LP GENERATOR FEATURES Interface (5V/3.3V[CMOS] input, 3.3V[CMOS] output) Single (XGA2: 65MHz)/dual (XGA: 32.5MHz) 8-bit Data input; dual port 8-bit output; SXGA auto detective Timing adjustable for horizontal clock output U\ U 4 .c CLKV GENERATOR CLKH GENERATOR OUTPUT SELECTOR RGBD ...
