MILPITAS, Calif., Oct. 23, 2013 (GLOBE NEWSWIRE) -- Intersil Corporation (Nasdaq:ISIL), a leading provider of innovative power management and precision analog solutions, today introduced the TW9990, a highly integrated analog video decoder that eliminates 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 ideal 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, iSuppli, a leading 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 poweranalog 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.


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.



  • NTSC/PAL/SECAM 4H adaptive comb filter Y/C separation
  • Two 10-bit ADCs and analog clamping circuit
  • Fully programmable static gain or automatic gain control for the Y channel
  • Built-in analog anti-alias filter
  • Image enhancement with peaking and CTI
  • Advanced synchronization processing and sync detection for handling non-standard and weak signals
  • Short-to-Battery and Short-to-Ground Detection
  • Available in a wettable flank QFN package, which enables visual solder inspection.
  • AEC-Q100 Grade 2 Qualified
