CS5843 - LCD Panel Timing Controller
ETC 2008/05/22 09:54GENERAL 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
* 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
