AUTOMOTIVE TEST

R&S RTP SCOPES AND MARVELL 88Q6113
MULTIPORT MULTIGIGABIT SWITCH MEET
WIDEBAND TEST REQUIREMENTS
by EE Staff
Rohde & Schwarz and Marvell announced that they have successfully
demonstrated compliance tests and debugging for high-speed digital interfaces
on the 88Q6113 multigigabit automotive
switch platform. Developments in advanced driver-assistance systems are creating a new approach to in-vehicle network
architecture design, the companies said,
adding that with today´s vehicles leveraging at least a hundred ECUs, the current
network architecture has reached its limits. The automotive industry is now focusing on a domain or zonal controller architecture to simplify network design and
maximize performance. A domain controller can potentially replace the functions
of many ECUs providing capabilities for
high-speed communications, sensor fusion, and decision-making, as well as providing support for high-speed interfaces
for cameras, radar, and lidar.
The Marvell 88Q6113 is suitable for
implementing a domain/zonal controller network architecture and is fully
compliant with the IEEE 802.3 automotive standard, delivering high bandwidth
with advanced routing and security. The
88Q6113 is an 11-port Ethernet switch
that supports RGMII/MII/RMII, SGMII,
XFI multi-speed SerDes (1/2.5/5/10 Gb/s),
and PCIe Gen 3.0, making it suitable for
integrating the full range of sensors required for advanced driver-assistance
systems and autonomous driving.
Signal integrity is a key factor for ensuring error-free data communication
with all these high-speed digital interfaces, the companies said. In particular,
the introduction of PCIe Gen 3.0 into the
automotive industry will bring new challenges to engineers not yet familiar with
the technology.

Rohde & Schwarz RTP oscilloscope

Rohde & Schwarz and Marvell reported that they were the first companies to
execute successfully 1000BASE-T1 compliance tests, for the Marvell´s 88Q2112
Ethernet transceiver, using an R&S RTO
oscilloscope. The latest improvements
to the R&S RTP oscilloscope family include the 16-GHz acquisition bandwidth
required to perform signal-integrity
tests and debugging for SerDes, LVDS,
PCIe Gen 3.0, MIPI, and more, as well as
automotive Ethernet interfaces all present in Marvell´s 88Q6113 multigigabit
automotive switch platform. The R&S
RTP includes real-time de-embedding
for signal-integrity analysis and has the
highest acquisition rate on the market.
In addition, the R&S RTP offers busmeasurement features supporting the
high-precision latency measurements
essential for debugging switches and networks, making this oscilloscope suitable
for automotive network test.
Dr. Nik Dimitrakopoulos, automotive market segment manager at Rohde
& Schwarz, commented, "With the

introduction of domain and zone controllers in automotive networks, engineers
will be faced with new challenges by the
integration of fast serial interfaces like
PCIe. Rohde & Schwarz is closely following the trends and test requirements in
this industry. The addition to our portfolio
of 16-GHz bandwidth for R&S RTP digital
oscilloscopes can assist the automotive
industry to overcome these challenges
and fits perfectly in this market. We are
very proud to assist Marvell in providing
quality assurance for their products to
their customers."
Tim Lau, senior director of product
marketing, Automotive Business Unit
at Marvell Semiconductor, added, "The
Marvell 88Q6113 extends our multigigabit leadership, with interfaces delivering
high bandwidth to connected controllers and sensors. We are proud to partner with Rohde & Schwarz to complete
compliance testing and deliver reliable,
high-quality solutions in this unique,
emerging market."
