1. OVERVIEW
The SD1010 is enhanced version of the SD1000 chip. It is an IC designed for dual-
interface XGA TFT LCD monitors. A dual-interface LCD monitor takes analog or
digital RGB signals from a graphic card of a personal computer, the exact same input
interface as a conventional CRT monitor. This feature makes a dual-interface LCD
monitor a true replacement for 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 SD1010. For digital
interface, the input data are first received by a TMDS receiver, and the 24/48 bit RGB
output data of TMDS receiver are then fed into the SD1010. The SD1010 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 any manual adjustment. The SD1010 then automatically scales the
input image to fill the full screen of the LCD monitor. The SD1010 can interface with
TFT LCD panels from various manufacturers by generating either 24-bit or 48-bit
RGB signal to the LCD panel based upon the timing parameters saved in the
EEPROM.
The SD1010 implements four advanced display technologies:
1. Advanced mode detection and auto-calibration without any external CPU assist
2. Advanced programmable interpolation algorithm
3. Stand-alone mode support, and
4. Advanced true color support with both dithering and frame modulation.
The SD1010 also provides distinguished system 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 SD1010 performs automatic input
mode detection and auto phase calibration, so the LCD monitor can ensure that the
A/D converters’ sample clock is precisely synchronized with the input video data, and
to preserve the highest image bandwidth for the highest image quality. Furthermore,
the SD1010 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 SD1010 implements many system support
features such as OSD mixer, error status indicators, 2-wire serial interface for both
EEPROM and host CPU interface, and low-cost IC package. Another important
contributing factor is that the SD1010 does not require external frame buffer memory
for the automatic image scaling and synchronization.
Figure 1 shows the block diagram of the SD1010 as well as the connections of
important system components around the SD1010.
