Feature
Description of ADE3700 Operation
Blocks Used Pages
Sync / Timing
Once an input source is selected, all available information on frequencies and SMEAS
25
Measurement
line/pixel counts is measured for the selected source and made available to
the MCU.
Mode Set
Once the MCU has determined the matching video mode or calculated a
GLBL
11
video mode using a GTF algorithm, the datapath is programmed to drive the LLK
18
flat panel. Clock frequencies for the internal memory and datapath are also

set at this time.

Autotune
When the MCU calls for an autotune, the MCU sets up an iterative loop to
DMEAS
47
search for the best phase, gain, offset, etc. At each step of the loop, the MCU LLK
18
kicks off a test in which the ADE3700 which performs extensive statistical
ADC
17
analysis of the incoming data stream. The results of the analysis are made

available to the MCU which is responsible for the optimization algorithm.
SRT

Digital Contrast / In response to user OSD control, the MCU can program single 8-bit registers SRGB
60
Brightness
that set brightness and contrast for each color channel independently.
White Point
In response to user OSD control, the MCU can program three 8-bit registers SRGB
60
Control
that set the white point for the output.
GAMMA
Adjustment
The MCU can program the gamma RAMs to implement 10-bit accurate color GAMMA
70
transformations.
sRGB Control
The SRGB block allows simple, intuitive color control with just a few registers. SRGB
60
Pattern
For production testing, the ADE3700 can be programmed by the MCU to
PGEN
54
Generation
output a wide set of test patterns.
Flicker Reduction For Smart Panel applications, the MCU can set up the flicker detection block FLICKER
68
to report any correlation with the polarity inversion signal. The MCU can then TCON
48
change the polarity inversion to a non-correlating pattern to eliminate flicker.
Backlight Control The ADE3700 provides two PWM outputs for direct control of the power
PWM
80
components in a typical backlight. The MCU sets up the registers and enables
the function.
Low Power State To enter a low power state, the MCU can gate of most of the clocks and put GLBL
11
the analog blocks into a low power standby state.
