4 / 35 page  1. OVERVIEW The SD1200 is an IC designed for analog-interface XGA/SXGA TFT LCD monitors. An analog-interface LCD monitor takes analog RGB signals from a graphic card of a personal computer, the exact same input interface as a conventional CRT monitor. This feature makes analog-interface LCD monitor a true replacement of a conventional CRT monitor. The analog input RGB signals are first sampled by six channels of 8-bit A/D converters, and the 48-bit RGB data are then fed into the SD1200. The SD1200 is capable of performing automatic detection of the display resolution and timing of input signals generated from various PC graphic cards. No special driver is required for the timing detection, nor does any manual adjustment. The SD1200 then automatically scales the input image to fill the full screen of the LCD monitor. The SD1200 can interface with TFT LCD panels from various manufacturers by generating 48-bit RGB signal to the LCD panel based upon the timing parameters saved in the EEPROM. The SD1200 provides two distinguished features to the TFT LCD monitor solution. The first one is “plug-and-play”, and the second one is “cost-effective system solution”. To be truly plug-and-display, the SD1200 performs automatic input mode detection and auto phase calibration, so that the LCD monitor can ensure the A/D converters’ sample clock to be precisely synchronized with the input video data, and to preserve the highest image bandwidth for the highest image quality. Furthermore, the SD1200 can generate output video even when the input signal is beyond the specifications, or no input signal is fed. For “cost-effective system solution”, the SD1200 implements many system support features such as OSD mixer, error status indicators, 2-wire I 2C serial interface for both EEPROM and host CPU interface, and low-cost IC package. Another important contributing factor is that SD1200 does not require external frame buffer memory for the automatic image scaling and synchronization. The SD1200 can handle input signal up to SXGA (1280x1024) resolution at 75Hz refresh rate, and produce output signal at SXGA resolution at 75Hz refresh rate (subject to the limitation of LCD panel). |
