5 / 88 page 5/88 ADE3XXX 1 General Description The ADE3XXX family of devices is capable of implementing all of the advanced features of today’s LCD monitor products. For maximum flexibility, an external microcontroller (MCU) is used for controlling the ADE3XXX and other monitor functions. The ADE3XXX architecture unburdens the MCU from all data-intensive pixel manipulations, providing an optimal blend of feature and code customization without incurring the cost of a 16-bit processor or memory. The key interactions between the monitor MCU and the ADE3XXX can be broken down into the features shown in the table below. Figure 1: ADE3XXX Block Diagram Table 1: ADE3xxx Features (Sheet 1 of 2) Feature Description of ADE3XXX Operation Blocks Used Pages Power Up / Initialize When power is first applied, the ADE3XXX is asynchronously reset from a pin. The MCU typically programs the ADE3XXX with a number of default values and sets up the ADE3XXX to identify activity on any of the input pins. All preconfigured values and RAMs, such as DVI settings, line-lock PLL settings, video input modes (YUV), OSD characters, LCD timing values (output sequencer), scale kernels, gamma curves, sRGB color warp, APC dithering, output pin configuration (OMUX), etc. can be preloaded into the ADE3XXX. The typical end state is that the ADE3XXX is initialized into a low power mode, ready to turn active once the power button is pressed.

Based on the activity monitors, the MCU chooses an input or power down state. SMEAS 32 YUV Port Analog Port DVI Port Scaler with SCLK F. Synth P. Gen FM F.
