Data Short To request the full datasheet, visit the TW8844 and TW8845 device pages. TW8844, TW8845 LCD Video Processor with Built-In Decoder, LVDS and TTL Inputs, OSD, TCON, LVDS, and MIPI Interface The TW8844 and TW8845 are highly integrated LCD Features video processors that incorporate many of the Analog Video Decoder features required to create a multipurpose LCD display system. This includes a high quality 2D comb Supports NTSC (M, 4.43) and PAL (B, D, G, H, I, M, NTSC/PAL/SECAM video decoder that supports N, N combination), PAL (60), SECAM with single-ended or differential composite video inputs, automatic format detection two independent TTL digital input interfaces (up to High quality adaptive 2D comb filter for both NTSC 24-bit each), two LVDS Open LDI input interfaces, two and PAL inputs separate high-quality scaler and deinterlacer engines, 10-bit ADC and analog clamping circuit (clamping is as well as a versatile OSD and EEPROM interface. 8-bit processing) The outputs include dual channel LVDS Open LDI, or TTL panel interfaces, as well as a separate MIPI-CSI2 Fully programmable static gain or automatic gain (TW8844) or pseudo BT.656 (TW8845) output. The control for the CVBS channel TW8844 and TW8845 can support input resolutions Programmable white peak control for the CVBS up to 1080p and can drive LCD panels at resolutions channel up 1920x1080. The TW8844 and TW8845 s video Selectable single-ended or differential CVBS inputs processing capability includes arbitrary H/V scaling, panoramic scaling, image mirroring, image PAL delay line for color phase error correction adjustment and enhancement, Automatic Contrast Image enhancement with 2D dynamic peaking/CTI Adjustment (ACA), etc. In addition, the TW8844 and TW8845 have new image diagnostic capabilities to Digital subcarrier PLL for accurate color decoding determine if the input video is corrupted. The feature Programmable hue, brightness, saturation, set and versatility of this device makes it an ideal contrast, sharpness solution for automotive LCD display applications.
