Sync / Timing
Once an input source is selected, all available information on frequencies and SMEAS
32
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 video GLBL
13
mode using a GTF algorithm, the datapath is programmed to drive the flat panel. LLK

Clock frequencies for the internal memory and datapath are also set at this time. SRT

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
19
kicks off a test in which the ADE3XXX which performs extensive statistical
ADC
18
analysis of the incoming data stream. The results of the analysis are made
SMUX

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

Digital Contrast / In response to user OSD control, the MCU can program single 8b registers that SRGB
64
Brightness
set brightness and contrast for each color channel independently.
White Point Control In response to user OSD control, the MCU can program three 8b registers that SRGB
64
set the white point for the output.
Gamma
Adjustment
The MCU can program the gamma RAMs to implement 10b accurate color
GAMMA
74
transformations.
SRGB Control
The SRGB block allows simple, intuitive color control with just a few registers. SRGB

Pattern Generation For production testing, the ADE3XXX can be programmed by the MCU to output PGEN
60
a wide set of test patterns.
Flicker Reduction For smart panel applications, the MCU can set up the flicker detection block to FLICKER
72
report any correlation with the polarity inversion signal. The MCU can then
TCON
55
change the polarity inversion to a non-correlating pattern to eliminate flicker.
HDCP
The ADE3XXX contains the BlockCipher and Decryption functions - interactions HDCP
27
over DDC are managed by the MCU for maximum flexibility. The MCU models
the slow (frame rate, e.g. 60 Hz) authentication handshaking and state machine
whereas the ADE3XXX handles the fast (line rate, e.g. 50 kHz) decryption state
machine.
Backlight Control The ADE3XXX provides two PWM outputs for direct control of the power
PWM
77
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 the GLBL
13
analog blocks into a low power standby state. The DVI block will still report
activity in standby, allowing "wake on connection" operation.
