TRADE NEWS: Agilent Technologies Introduces Enhanced Solution for PCI Express® 3.0 Receiver Characterization J-BERT N4903B Handles PCIe® 3.0 SKP Ordered Set Length Changes During Receiver Characterization
SANTA CLARA, Calif. --(Business Wire)--
Agilent (News - Alert)�Technologies Inc. (NYSE:�A) today announced an enhanced solution
for PCI Express® 3.0 receiver characterization, at DesignCon.
The Agilent
PCIe® 3.0 receiver characterization solution provides
complete and accurate receiver tolerance test results while minimizing
R&D effort. The new J-BERT software (revision 7.40) enables testing of
PCIe 3.0 receiver designs that adjust the length of the 128b/130b
encoded filler symbols-also known as SKP ordered sets-as needed for
clock compensation.
Using the Agilent test set, design and test engineers in the
semiconductor and computer industry can accurately characterize and
verify standard compliance of PCIe receiver ports in ASICs, add-in cards
and motherboards.
Since the release of revision 3.0 of the PCI (News - Alert) Express specification, the
8-GT/s interface has been designed into many computer platforms. A
common reference clock often is used for PCIe designs, but more and more
designs now require a separate reference clock architecture with
independent spread spectrum clocking (SSC) such as a PCIe-over-cable
link. When designers use separate reference clocks, they need to
compensate for small differences in the clock rate on the transmitter
and receiver sides to avoid buffer overflow. Clock compensation can be
required even for common reference clock designs on motherboards, in the
presence of SSC or when using multiplying phase-locked loops. The PCI
Express standard requires this compensation to be accomplished by adding
SKP symbols to (or removing them from) the nominal SKP ordered set.
Agilent's new J-BERT N4903B high-performance serial bit-error ratio
tester software enables receiver testing in cases where the SKP ordered
set length is changed by the device under test in loopback mode. The
J-BERT error detector can now ignore SKP ordered sets when counting
errors, even when they deviate from the original length sent out by the
pattern generator. When engineers debug their designs, they can monitor
SKP ordered set counters in the error detector.
"For PCIe 3.0 chipset and board designers, our solution's ability to
handle adjustments of PCIe 3.0 SKP ordered sets during receiver jitter
tolerance characterization fills a critical need," said Michael
Fleischer-Reumann, strategic product planner for Agilent's Digital
Photonic Test Division. "The flexible architecture of our J-BERT, along
with our long expertise in PCI Express receiver testing, allowed us,
once again, to address emerging test challenges."
With this enhancement, Agilent continues to broaden its complete and
accurate PCIe 3.0 receiver test solution, which can be used for
characterizing against the base specification as well as the
card-electro-mechanical specification.
The Agilent receiver test solution encompasses the J-BERT
N4903B high-performance serial BERT, the N4916B
de-emphasis signal converter, the N4915A-014 PCIe 3.0-compliant
calibration channels, the 81150A
or 81160A pulse function arbitrary noise generator, an Infiniium
90000 or 90000
X-Series high-performance oscilloscope, and N5990A-101
and N5990A-301 test automation and link training software. For
motherboard testing, the N4880A
reference clock multiplier is available.
Benefits of the Agilent PCIe 3.0 receiver characterization solution
include:
-
Support for PCIe receiver testing with both common and separate
reference clocks by the ability to count errors while ignoring SKP
ordered set length changes.
-
Accurate and repeatable receiver test results enabled by stress
calibration software, adjustable pre- and post-cursor de-emphasis,
J-BERT's built-in PCIe 3.0-compliant jitter and sinusoidal
interference sources, periodic jitter-sweep functionality, a 100-MHz
reference clock multiplier and PCIe 3.0-compliant calibration channels.
-
Higher R&D efficiency enabled by PCIe 3.0 stress calibration and
receiver test automation software and the PCIe 3.0 link-training
suite, which controls J-BERT's pattern sequencer to bring the device
under test into loopback mode.
-
Investment protection enabled by using Agilent instruments that can be
repurposed for accurate characterization for multiple gigabit test
applications, such as USB, SATA, MIPI M-PHY, TBT and QPI.
Agilent will demonstrate its enhanced PCI Express 3.0 receiver
characterization solution at DesignCon
2013, Jan. 28-31, at the Santa Clara Convention Center, Booth 201.
Agilent offers a wide selection of high-speed digital solutions,
including essential tools to pinpoint problems, optimize devices and
deliver results for design and simulation.
