52 / 88 page ![]() Output Sequencer Block ADE3XXX 52/88 2.15 Output Sequencer Block The output sequencer module provides timing for the output video interface. It allows sufficient flexibility to support a broad range of Smart Panel applications as well. The timing unit is based on horizontal and vertical counters, which are locked with the input video stream. Frame Synchronization Due to the limited pixel memory of the chip, the output active video needs to be perfectly synchronized with the input active video. This mode of operation is called Frame Lock. Timing Unit The timing unit consists of a 12-bit horizontal and a 12-bit vertical counter, synchronized with the input video stream. Signal Generation The signal generation unit generates all fixed control signals like hsync, vsync and data enable as well as those required to run the internal data path. Also included, a generalized timing section supports flat panel TCON signals like polarity and other control signals. Figure 4: Output Sequencer Block Diagram Figure 5: Frame Lock Operation |
