BEAVERTON, Ore., June 23, 2015 /PRNewswire/ -- Tektronix, Inc.,
the world's leading manufacturer of oscilloscopes, today announced
the industry's first commercially available oscilloscope-based
solution for MIPI® C-PHYSM physical layer transmitter
characterization and debugging. The new solution allows engineers
developing next-generation camera technologies using the C-PHY 1.0
interface to conduct in-depth analyses, debugging and
characterization of their designs.
Published in September 2014, the
MIPI C-PHY standard presents a number of significant test and
measurement challenges. The most significant is the use of
three-level signaling that is transmitted as a single-ended signal
over three wires. The receiver, however, sees these signals as
differential. This requires a unique clock recovery mechanism to
plot the eye diagram for analysis, which must work even under
stressed eye conditions. Tektronix C-PHY Essentials, a new analysis
and debugging software solution for C-PHY testing, fully supports
the demanding C-PHY test requirements.
"With an up to 17.1 Gb/s data rate over a nine-wire interface,
C-PHY provides the performance needed for high megapixel count
image sensors along with low power consumption," said Brian Reich, general manager, Performance
Oscilloscopes, Tektronix. "Our solution for C-PHY transmitter
testing allows engineers to detect issues early on in the product
development phase and confidently assures transmitter devices'
performance and interoperability."
Among the early implementers of C-PHY is OmniVision Technologies
Inc., a leading developer of advanced digital imaging solutions.
OmniVision's new OV23850 and OV21840, both being 20+ megapixel
image sensors designed for the next generation of flagship
smartphones, have implemented the C-PHY interface under the current
specification. Using the C-PHY Essentials analysis software,
OmniVision and Tektronix were able to successfully validate and
characterize the C-PHY interface used on the two new sensors.
"OmniVision is excited to have Tektronix's oscilloscope-based
C-PHY Essentials software for validating the next generation MIPI
interface. With its three-wire signaling, C-PHY represents a
significant design and test challenge," said Paul Gallagher, senior director of marketing and
business development at OmniVision. "With the help of Tektronix
C-PHY Essentials, we were able to easily set up cameras utilizing
the OV23850 and OV21840 sensors and confirm the C-PHY interface's
compliance with the MIPI specification."
Receiver Characterization
While the C-PHY Essential software is designed for TX
characterization, it can also be used by designers for receiver
calibration. For receiver calibration, a user needs the ability to
make various rise and fall time measurements and calibrate to a
stressed eye with different impairments such as DCD as recommended
by the C-PHY compliance test specification. As such, C-PHY TX
analysis software can assist designers with receiver calibration
through use of the eye diagram analysis function.
Working with solution partner The Moving Pixel Company, the
Tektronix C-PHY solution includes a four-lane C-PHY traffic
generator, single-lane oscilloscope based C-PHY protocol decoder
and C-PHY termination board. The traffic generator can be also used
for functional validation of the receiver. The protocol decoder is
the industry's first C-PHY decoder that runs on an oscilloscope.
The Moving Pixel Company also offers a four-lane termination board
that supports C-PHY and D-PHY, the industry's first with support
for both of these PHYs on the same board.
