CS5843

CS5843 LCD Panel Timing Controller (15") GENERAL DESCRIPTION The CS5843 is a TFT-LCD timing controller, which is applicable to 6-bit data XGA (1024*768), SXGA (1280*1024). CS5843 can update the response timing for display mode of XGA and SXGA automatically. CS5843 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 10. FEATURES • CS5843 Interface (5V/3.3V[CMOS] input, 3.3V[CMOS] output) • Single (XGA2: 65MHz)/dual (XGA: 32.5MHz) 6-bit Data input; dual port 6-bit output; SXGA auto detective • Timing adjustable for horizontal clock output 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 3U HOL PL QD U\ POWER ON RESET STH1/STH8 GENERATOR POL/SHC GENERATOR CLKV GENERATOR STV1/STV3 GENERATOR LP GENERATOR CLKH GENERATOR HD DCLK1 INV PNDCLK PNVD PNHD POLIN ICMD(2~1) DATAHT SXMD CLKV STV1 STV2 CLKH STH1 STH8 LP POL SHC RLSC PNHMS PLMD SCMD SET HITAENB CLKHT ODDGO(5~0) EVENGO(5~0) ODDRO(5~0) EVENRO(5~0) ODDBO(5~0) EVENBO(5~0) HMS1 HMS2 DATA-PATH DELAY OUTPUT SELECTOR INPUT SELECTOR SAMPLE POLARITY RGBD GT(2~1) ODDRI(5~0) ODDGI(5~0) ODDBI(5~0) EVENRI(5~0) EVENGI(5~0) EVENBI(5~0) CS5843 Myson Century, Inc.
