ROHM Semiconductor LAPIS ML86640 Digital Video Encoder

ROHM Semiconductor LAPIS ML86640 Digital Video Encoder is compatible with the NTSC/PAL format. The encoder converts digital image input, such as ITU-R BT.656, ITU-R BT.601, etc., to analog image signals. Supported digital image input is RGB 24-bit, YCbCr 24-bit/16-bit/8-bit, and ITU-R BT.656. Its input scan mode supports both interlace and progressive.

The analog image output is an NTSC/PAL composite signal 1 ch. P/I conversion is equipped to output progressive digital data as interlace signals. An output signal can be directly connected to an image display apparatus. The ROHM Semiconductor LAPIS ML86640 Digital Video Encoder does not require external video amplifiers.
