TW8836 FN8645 Rev 8.00 Aug 8, 2019 LCD Video Processor with Built-In Decoder, TTL/LVDS Inputs, MCU, OSD, and TTL/LVDS Panel Interface Features The TW8836 is a highly integrated LCD video processor that incorporates many of the features required to create a multipurpose LCD display system into a single package. This includes a high quality, 2D comb NTSC/PAL/SECAM video decoder, triple high-speed RGB ADCs, an LVDS and TTL digital input interface,a high-quality scaler and deinterlacer, and a versatile OSD, with a high-performance output panel interface for MCU and LVDS or TTL. The TW8836 can support input resolutions up to 1080p and can drive LCD panels at resolutions up to 1366x768. The TW8836’s video processing capability includes arbitrary H/V scaling, panoramic scaling, image mirroring, image adjustment and enhancement, and black and white stretch. The feature set and versatility of this device makes it an ideal solution for in-car LCD display applications and portable display applications such as pico projectors. Analog Video Decoder • NTSC (M, 4.43) and PAL (B, D, G, H, I, M, N, N combination), PAL (60), SECAM with automatic format detection • Three 10-bit ADCs and analog clamping circuit • Fully programmable static gain or automatic gain control for the Y or CVBS channel • Programmable white peak control for the Y or CVBS channel • Software selectable analog inputs allow composite, S-video, analog YPbPr, or RGB • High quality adaptive 2D comb filter for NTSC/PAL inputs • PAL delay line for color phase error correction • Image enhancement with 2D dynamic peaking/CTI • Digital subcarrier PLL for accurate color decoding • Programmable hue, brightness, saturation, contrast, sharpness • Selectable differential or single-ended CVBS input • Digital horizontal PLL and advanced synchronization processing for VCR playback and weak signal performance • High quality horizontal and vertical filtered-down scaling with arbitrary scale-down ratio • Up to 2CH differential or 4CH single-ended CVBS input • Supports detection of Macrovision copy protection Applications • In-car display • Pico projector and portable media player • Portable DVD and DVR players Related Literature For a full list of related documents, visit our website: • TW8836 device page YOUT GPLL YIN0 ~ 3 C V BT.656 BT.656 Encoder Down Scaler 2D-Comb Decoder VIN0 ~ 1 10-bit ADC CVBS S-Video Component ARGB MU X CIN0 ~ 1 Y Diagnostic Dither Gamma CSC TCON Measurement LVDS-RX LVR DVDD R-C OSC Serial RGB SPI OSD DTV I/F LVDS TTL 24bit LVDS TX SSPLL1 PCLK SSPLL2 MCUCLK Host Interface OSC I2C MCU SPI Interface GPIO Interrupt SPI Flash Touch Screen Controller TCON I/F LVDS X+/-, Y+/AUX0 ~ 3 FIGURE 1.
