Short-Form Datasheet TW8846, TW8847 R33DO0004EU0400 Rev.4.00 LCD Video Processor with Decoder, LVDS, TTL, MIPI, Image Enhancement, Sep 17, 2021 and Video Integrity Diagnostic The TW8846 and TW8847 are highly integrated LCD Features video processors that incorporate many of the features Analog Video Decoder required to create a multipurpose LCD display system. Supports NTSC (M, 4.43) and PAL (B, D, G, H, I, M, These features include a high quality 2D comb N, N combination), PAL (60), and SECAM with NTSC/PAL/SECAM video decoder that supports automatic format detection single-ended or differential composite video inputs, two independent TTL digital input interfaces (up to 24-bit High quality adaptive 2D comb filter for both NTSC each), two LVDS Open LDI input interfaces, two and PAL inputs separate high quality scaler and de-interlacer engines, 10-bit ADC and analog clamping circuit (clamping is and a versatile OSD and an EEPROM/SPI interface. The 8-bit processing) outputs include dual channel LVDS Open LDI or TTL panel interfaces, and a separate MIPI-CSI2 output in the Fully programmable static gain or automatic gain TW8846 and a pseudo BT.656 output in the TW8847. control for the CVBS channel The TW8846 and TW8847 can support input resolutions Programmable white peak control for the CVBS up to 1080p and can drive LCD panels at resolutions up channel to 1920x1080. The video processing capabilities include Selectable single-ended or differential CVBS inputs 10-bit color processing, arbitrary H/V scaling, panoramic scaling, image mirroring, image adjustment and PAL delay line for color phase error correction enhancement, black and white stretch, and automatic Image enhancement with 2D dynamic peaking/CTI contrast adjustment. The TW8846 and TW8847 have improved image diagnostic capabilities to determine if Digital subcarrier PLL for accurate color decoding the input video is corrupted. The feature set and Programmable hue, brightness, saturation, contrast, versatility of this device makes it an ideal solution for and sharpness automotive LCD display applications. Digital horizontal PLL and advanced synchronization Applications processing for superior VCR playback and weak Automotive display signal performance Industrial/military displays Up to 3CH differential or 6CH single-ended CVBS input Portable/consumer displays Digital Input Support Supports BT.656, 8-bit and 16-bit BT.601, and BT.1120 video formats Supports YCbCr/RGB 24-bit input up to 1080p resolution Two single channel LVDS open LDI inputs, up to 104MHz for each channel Dual channel LVDS open LDI input, up to 150MHz in Dual mode (75MHz per channel) Supports RGB565 + BT.656 at the same time R33DO0004EU0400 Rev.4.00 Page 1 of 3 Sep.17.21 2018 Renesas ElectronicsTW8846, TW8847 TFT Panel Support Built-in programmable timing controller Supports 3, 4, 6, or 8 bits per pixel up to 16.8 million colors with built-in dithering engine Supports single channel LVDS panels up to 1920x720 resolution (104MHz) Supports dual channel LVDS and digital panels (TTL) up to 1920x1080 resolution (150MHz) Font Based On-Screen Display Four windows font OSD with bordering/shadow 13824 bytes programmable font RAM and 1024 characters display RAM 1/2/3/4 bits per pixel Supports variable width (12/16), height (2~32) SPI Flash Based On-Screen Display Supports fast register initialization by SPI-DMA Nine bitmap-based OSD windows in two layers through SPI with alpha blending between layers Supports 4/6/8 bits/pixel Supports RLE decompression for two windows Shares pins with EEPROM interface EEPROM Interface EEPROM interface for fast boot register initialization Shares pins with SPI Flash memory interface Image Processing Two high quality scalers with both up/down scaling support Built-in 2D de-interlacing function Supports programmable cropping of input video and graphics Automatic Contrast Adjustment (ACA) on one scaler path Independent RGB gain and offset controls 10-bit per color processing 10-bit image enhancement processing and 10-bit Gamma correction Clock Generation Spread spectrum PLL integrated to each scaler path Programmable modulation frequency and spread width Timing Controller (TCON) Supports programmable interface signals for control Column (source) driver/Row (gate) driver MIPI-CSI2 Output (TW8846 only) Four lane MIPI-CSI2 output port (1Gb/lane) Supports YUV422 and 24-bit RGB data formats Pseudo BT.656 Output (TW8847 only) Independent BT.656 compatible YCbCr (4:2:2) output format YCbCr (4:2:2) output generated from all input paths Output can be processed through the scaler path or bypass scaling all together R33DO0004EU0400 Rev.4.00 Page 2 of 3 Sep.17.21
