5 / 89 page 5/89 ADE3700 1 General Information The ADE3700 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 ADE3700 and other monitor functions. The ADE3700 architecture unburdens the MCU from all data-intensive pixel manipulations, providing an optimal blend of features and code customizing without incurring the cost of a 16-bit processor or memory. The key interactions between the monitor MCU and the ADE3700 can be broken down into the features shown in the table below. Figure 1: ADE3700 Block Diagram Table 1: ADE3700 Features (Sheet 1 of 2) Feature Description of ADE3700 Operation Blocks Used Pages Power-up / Initialize When power is first applied, the ADE3700 is asynchronously reset from a pin. The MCU typically programs the ADE3700 with a number of default values and sets up the ADE3700 to identify activity on any of the input pins. All pre- configured values and RAMs, such as DVI settings, line-lock PLL settings, OSD characters, LCD timing values (output sequencer), scale kernels, gamma curves, sRGB color warp, APC dithering, output pin configuration (OMUX), etc. can be pre-loaded into the ADE3700. The typical end state is that the ADE3700 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 25 LCD Timing Controller FM Freq.
