Low Power NTSC/PAL Video Decoder with Differential
CVBS Inputs and MIPI-CSI2 Output Interface
TW9992
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 as well as S-Video. 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.
