MILPITAS, Calif., Feb. 16, 2015 /PRNewswire/ -- Intersil
Corporation (NASDAQ: ISIL), a leading provider of innovative power
management and precision analog solutions, today announced the
TW9984 four-channel analog video decoder with built-in analog video
encoder for around-view parking assist applications, providing
improved safety for drivers and pedestrians. The TW9984 is based on
Intersil's market leading video decoder technology and replaces up
to nine discrete components with a single chip. It delivers the
industry's best analog decoding performance resulting in excellent
picture quality to generate 360-degree surround images for advanced
driver assistance systems (ADAS).
ADAS is a rapidly growing market segment, driven largely by
safety requirements in all light passenger vehicles. Most new
vehicles today have options including around-view camera systems
for parking assistance and blind spot detection/elimination. The
National Highway Traffic Safety Administration (NHTSA) estimates
that rearview cameras can reduce back-over fatalities by more than
50 percent. Accordingly, automotive image sensor penetration in
vehicles is increasing, and ABI Research estimates shipments will
reach 197 million by 2020.
The Intersil TW9984 analog video decoder and encoder provides
motorists with detailed, high-quality video, enhancing their
ability to see objects not just behind the car but around the
entire vehicle. An around-view monitor system, also referred to as
a surround view monitor, processes video from four cameras and then
combines the four images into a single birds-eye, top-down 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 and parking.
The TW9984 integrates four high quality NTSC/PAL analog video
decoders with 10-bit analog-to-digital converters (ADCs) to support
four analog camera inputs simultaneously. A flexible digital output
interface makes it easy for the system designer to send the images
to a processor that can then combine the four images into a single
unified around-view image. The on-chip analog video encoder
provides the ability to transmit the combined video as a standard
analog composite signal to the head unit display. The TW9984 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 is a leader in multi-channel video and is at the
forefront of ADAS around-view camera applications," said
Philip Chesley, senior vice
president of Precision Products at Intersil. "The decoder's
innovative architecture and high level of integration enables an
ultra-clear image to increase driver and pedestrian safety, as well
as avoid vehicle damage."
Key Features and Specifications
- Integrates four NTSC/PAL analog video decoders and 10-bit ADCs
with differential, pseudo differential and single-ended inputs
- Integrates one analog video encoder to re-encode video to CVBS
format
- Integrates programmable automotive short diagnostics --
short-to-battery and short-to-ground detection -- on each
differential input channel
- Supports 108MHz time multiplexed ITU-R BT.656 format to output
four channels over a single 8-bit data bus
- Integrated PLL generates the 108MHz output while using a lower
cost 27MHz crystal oscillator on the board
- Consumes approximately 100mW per decoder channel, which is up
to 20 percent less per channel than equivalent solutions
- AEC-Q100 qualified
Availability
The TW9984 four-channel analog video
decoder and encoder is available now in a 10mm x 10mm, WQFN package
and is priced at $5.00 USD in 1k
quantities. The TW9984AT-NA1-EVAL evaluation board is offered with
a user manual, schematics and firmware. For more information on the
TW9984 and evaluation board, please visit:

The TW9984 can be combined with the ISL78302 dual LDO, ISL78322
synchronous buck regulator and the ISL78228 dual synchronous
step-down DC/DC buck regulator to manage power rails for the
TW9984, memory, DSP or FPGA in an around-view ADAS application.
