Intersil Corporation has introduced the TW9990, a highly integrated analogue video decoder that is intended to eliminate the need for external op amps while enabling performance advantages through programmable short-to-battery and short-to-ground detection. The TW9990 video decoder is suitable for automotive rear camera displays and other camera systems.
Automotive rear camera displays have become a popular driver safety feature. According to Edmunds market research, 70 percent of 2012 vehicles were outfitted with rear cameras. Also, IHS, the market research firm, reports that nine in 10 new cars have console screens as an option. The quality of the video – along with the cost and footprint of the camera solution – are critical factors when adding this important safety feature to new vehicles.
The TW9990 video decoder is a low power analogue video decoder that supports NTSC/PAL/SECAM single-ended, differential, and pseudo differential composite video inputs as well as S-Video. A single 27MHz crystal is all that is needed to decode all analog video standards. Typical power consumption is approximately 100mW for composite inputs. A power-down mode further reduces consumption.
