Lattice Introduces Image SensorExtender Reference Design
Low-Cost Solution Uses Inexpensive Twisted-Pair Cable to Separate
Image Sensors up to Eight Meters From Image Signal Processors
HILLSBORO, OR -- (Marketwired) -- 04/12/13 -- Lattice Semiconductor
Corporation (NASDAQ: LSCC) today announced the SensorExtender(TM)
reference design that offers a low-cost approach to remotely locate
image sensors up to eight meters away from the image signal processor
(ISP) and transmit and receive video signals at resolutions that
range up to 720p60 and 1080p30.
The reference design uses inexpensive low-cost Cat5E cable to carry
high-definition video and to send I2C sensor control signals from the
ISP during the vertical blanking period. Three twisted pairs carry
the video and commands while a fourth pair provides power and ground
to the remotely located sensors.
This solution serves applications that require image sensors to be
separated from the image signal processor, which are often placed in
tight spaces without room for adjacent ISPs to process the image.
Typical applications include medical probes, large screen TVs with an
integrated HD camera, surveillance domes, piping inspection ports,
and point-of-sale scanners. The SensorExtender may link a single
sensor to an ISP or connect a number of sensors to a central
"Many customers and partners wanted a low-cost digital solution to
put image sensors in difficult-to-reach places far from the ISP as
well as benefit from the clarity and quality of HD images," said Ted
Marena, Director of Solutions Marketing at Lattice Semiconductor.
"The combination of our video expertise and the flexibility of our
low- cost FPGAs enables camera system designers to easily and
inexpensively implement this compelling solution."
The reference design uses two Lattice
MachXO2(TM) low density FPGAs: one is placed next to the image sensor
and the other is located just before the ISP. A single twisted pair
CAT5E/6 cable connects the two.
The SensorExtender solution offers a variety of interfaces (before
serialization) for CSI-2, HiSPi, parallel, or sub-LVDS image sensors
along with support for extending two or more image sensors.
Additionally, the reference design allows parallel or serial ISP
interfaces (after-deserialization). Designers can configure parallel
interfaces to handle 1.8V, 2.5V, or 3.3V LVCMOS levels.
The reference design is tested with the Aptina MT MT9M024 and the
Lattice HDR-60 camera development kit's base board.
