Renesas TW8845-LB1-CE

The TW8844 and TW8845 are highly integrated LCD video processors that incorporate many of the features required to create a multipurpose LCD display system. This includes 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 deinterlacer engines, as well as a versatile OSD and EEPROM interface. The outputs include dual channel LVDS Open LDI, or TTL panel interfaces, as well as a separate MIPI-CSI2 (TW8844) or pseudo BT. 656 (TW8845) output.
