Low power analog video decoder eliminates the need for external op amps
The TW9990 video decoder is ideal for automotive rear camera displays and other camera systems.
The TW9990 video decoder is a low power analog video decoder that supports NTSC/PAL/SECAM single-ended, differential, and pseudo differential composite video inputs as well as S-Video. A single 27 MHz crystal is all that is needed to decode all analog video standards. Typical power consumption is approximately 100 mW for composite inputs. A power-down mode further reduces consumption.
Most automotive analog cameras are cabled as differential twisted pair to reduce common mode noise. Traditional analog video decoders only support single-ended inputs, meaning automotive system designers must place a video op amp in front of the decoder to convert differential signals to single-ended.
The TW9990 video decoder eliminates the need for the external op amp and the associated cost, as it supports differential composite video signals directly, and has built-in programmable short-to-battery and short-to-ground detection. This is an essential functionality required by OEMs when supporting a differential signal input.
Availability and Pricing
The TW9990 video decoder is available now in a compact 32-lead 5×5 mm WFQFN in bulk tray packaging at $2.60 each in 1,000-units quantities. It is also offered in tape and reel packaging at $2.65 each. A user friendly evaluation board, TW9990-NA1-GR-EVAL, is also available for $599.
