Highly integrated TW9966 enables excellent picture quality and detailed 360-degree surround images to improve driver safety
02 Jun 2014
MILPITAS, Calif., June 2, 2014 (GLOBE NEWSWIRE) -- Intersil Corporation (Nasdaq:ISIL), a leading provider of innovative power management and precision analog solutions, today announced the TW9966 four-channel analog video decoder with a built-in analog video encoder for around-view automotive applications. Based on Intersil's market leading multi-channel video surveillance technology, the TW9966 features four analog video decoders and an analog video encoder integrated into a single chip, replacing up to five discrete components to simplify design and save board space. The TW9966 video decoder and encoder is optimized for automotive applications, offering the industry's best analog decoding performance resulting in excellent picture quality for generating 360-degree surround images for drivers.

To increase driver safety and reduce damage to vehicles, many leading automotive original equipment manufacturers (OEMs) are providing around-view technology as an option in their latest models. An around-view monitor, also referred to as a surround view monitor, processes video from four cameras and then combines the four images into a single birds-eye view as if a camera was stationed directly above the vehicle. The monitor helps drivers visually confirm the vehicle's position relative to surrounding objects for easy maneuvering. The Intersil TW9966 decoder and encoder provides consumers with superb, detailed, high-quality video, enhancing their ability to see objects around the car.
The TW9966 is able to deliver best-in-class video quality from analog camera sources because of Intersil's precision analog-to-digital converter (ADC) technology and proprietary comb filter integrated on chip.The TW9966 integrates four high quality NTSC/PAL analog video decoders with 10-bit ADCs to support: four analog camera inputs, a flexible digital output interface that sends the images to a processor that combines the four images into the unified around-view module, and one analog video encoder that outputs the combined video as an analog composite signal to the display, all in a single-chip solution. The TW9966 also incorporates analog anti-aliasing filters on each channel input to further reduce component count. The high level of integration helps to simplify the system design and minimize the solution footprint to preserve critical board space.
Intersil's new TW9966 video decoder and encoder provides performance, quality and flexibility to enable automotive designers to program multiple system architecture options in terms of routing multiple channels of video to the back-end processor or FPGA, resulting in optimized board design and reduced cost. The TW9966 offers a digital output interface to support up to three different configurations: standard ITU-R BT.656 format output on four 8-bit buses at 27MHz; time multiplexed byte interleaved output to send two channels on a single 8-bit bus at 54MHz; or all four channels on a single 8-bit bus at 108MHz. The TW9966 also includes a phased-lock loop (PLL) to generate the 54MHz or 108MHz output, requiring only a lower cost 27MHz oscillator as a reference.
"Intersil has been a leader in multi-channel decoder technology supporting complex security surveillance systems for years," said Philip Chesley, vice president of Precision Products at Intersil. "The performance we've been able to deliver in a single chip through our innovative architecture uniquely addresses the requirements of the latest vehicles while providing drivers with premium analog video decoding quality and a better experience to improve overall safety."
