TW8847

The TW8846 and TW8847 are highly integrated LCD video processors that incorporate many of the features required to create a multipurpose LCD display system. These features include a high quality 2D comb NTSC/PAL/SECAM video decoder that supports single-ended or differential composite video inputs, two independent TTL digital input interfaces (up to 24-bit each), two LVDS Open LDI input interfaces, two separate high quality scaler and de-interlacer engines, and a versatile OSD and an EEPROM/SPI interface. The outputs include dual channel LVDS Open LDI or TTL panel interfaces, and a separate MIPI-CSI2 output in the TW8846 and a pseudo BT. 656 output in the TW8847.

The TW8846 and TW8847 can support input resolutions up to 1080p and can drive LCD panels at resolutions up to 1920x1080. The video processing capabilities include 10-bit color processing, arbitrary H/V scaling, panoramic scaling, image mirroring, image adjustment and enhancement, black and white stretch, and automatic contrast adjustment. The TW8846 and TW8847 have improved image diagnostic capabilities to determine if the input video is corrupted. The feature set and versatility of this device makes it an ideal solution for automotive LCD display applications.
