TW9992

Low Power NTSC/PAL Video Decoder with Differential CVBS Inputs and MIPI-CSI2 Output Interface

The TW9992 is a low power NTSC/PAL analog video

decoder that is designed for automotive applications.

It supports single-ended, differential and pseudo

differential composite video inputs. Integrated

short-to-battery and short-to-ground detection,

advanced image enhancement capabilities such as

the programmable Automatic Contrast Adjustment

(ACA) and the MIPI-CSI2 output interface make the

TW9992 an ideal solution for demanding automotive

camera applications.
