The ADE3800 family of devices is capable of implementing all of the advanced features of todays
LCD monitor products. For maximum flexibility, an external microcontroller (MCU) is used for
controlling the ADE3800 and other monitor functions.

The ADE3800 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 ADE3800 can be
broken down into the features shown in Table 1.

Description of ADE3800 Operation
Blocks Used Pages
Power-up / Initialize
When power is first applied, the ADE3800 is asynchronously reset from a pin.
The MCU typically programs the ADE3800 with a number of default values and
sets up the ADE3800 to identify activity on any of the input pins. All pre-
configured values and RAMs, such as 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 ADE3800. The typical end state is that the ADE3800 is
initialized into a low power mode, ready to turn active once the power button is
pressed.

Activity Detect
When the monitor has been powered on, the inputs can be monitored for active SMEAS
video sources. Based on the activity monitors, the MCU chooses an input or
power down state.
