J-BERT Enables Robust Receiver Designs for Next-Generation, Multigigabit Serial
Interfaces Such as QPI, 10GBASE-KR, SATA and USB 3
SANTA CLARA, Calif.--(Business Wire)--
Agilent Technologies Inc. (NYSE:A) today announced the addition of a 4-tap
de-emphasis signal converter N4916B, an ultraflexible SSC injection and a SATA
ISI channel to its J-BERT N4903B high-performance serial BERT. The new
capabilities enable R&D and test engineers to accurately characterize receiver
ports and channels of multigigabit serial bus interfaces, such as Quickpath
Interconnect (QPI), Hypertransport, PCI Express, DisplayPort, SerialATA, USB3,
CEI, 10GBASE-KR, 40GBASE-KR and memory interfaces.
4-Tap De-emphasis Signal Converter
The de-emphasis technique is used in the transmission of digital electrical
signals at gigabit data rates. De-emphasis is a signal pre-distortion to
compensate for signal degradations that occur when transmitting electrical
signals with gigabit rates over PC board traces, backplanes or long cables.
Agilent`s new de-emphasis signal converter, the N4916B, allows users to emulate
transmitter de-emphasis with one pre- and two post-cursors, as well as
individually adjust de-emphasis levels up to 12.0 dB. With its DC-coupled
outputs, the signal converter tolerates even unbalanced pattern streams. The
N4916B is transparent to jitter, enabling emulation of real-world de-emphasis
and jitter conditions that a receiver is expected to tolerate. Agilent`s new
de-emphasis signal converter can be used as front-end for J-BERT N4903A/B,
ParBERT or other gigabit pattern generators.
Besides its de-emphasis capabilities, the N4916B offers a unique clock-doubling
option, which enables error, jitter and eye analysis with J-BERT N4903B of
transmitters using half-rate clocks.
Ultraflexible SSC Injection
The spread spectrum clocking (SSC) injection is becoming more common for
high-speed interconnects. SSC modulates the operating frequency of a circuit
slightly to spread its radiated emissions over a range of frequencies.
J-BERT N4903B`s SSC option now provides more flexible and arbitrary SSC
injection capabilities that can be combined with sinusoidal jitter injection,
helping R&D engineers emulate worst-case and real-world SSC conditions,
especially for SATA, SAS and USB3 receivers.
SATA ISI Channel
The new Agilent SATA ISI Channel N4915-60001 helps R&D and test engineers easily
reproduce precise SATA compliant stress conditions for the receiver stress test
when used in combination with J-BERT N4903B.
"We are very proud to offer the industry`s leading jitter tolerance test
solution," said Jürgen Beck, general manager of Agilent`s Digital Photonic Test
product line. "By adding multitap de-emphasis, ultraflexible SSC and SATA ISI
channel, we significantly simplify the accurate characterization of the
next-generation of serial interfaces operating above 5 Gb/s. With this
introduction we confirm our commitment to enable R&D and validation teams to
release robust high-speed digital interfaces for the next generation of
computer, consumer and communication devices."
Benefits of the Agilent N4916B de-emphasis signal converter include:
* Easy-to-emulate transmitter de-emphasis with individually adjustable
de-emphasis of 0.0 dB to 12.0 dB in 0.1 dB steps for one pre- and two
post-cursors. Tolerates unbalanced pattern and is jitter transparent.
* Ability to optimize the receiver`s jitter budget by compensating for signal
degradations caused by the test setup, cabling and test board ("de-embedding")
by using signal de-emphasis.
* Flexible usage as de-emphasis front-end for J-BERT N4903A/B, ParBERT or other
gigabit pattern generators.
* Accurate eye, jitter and error analysis of half-rate clocked transmitters with
J-BERT N4903B by using the clock-doubler option.
Benefits of the Agilent J-BERT N4903B Software 6.1 and SATA ISI Channel
include:
* Robust receiver designs by emulating real-world SSC effects via file upload of
arbitrary SSC profiles.
* Compliant SAS and SATA injection of SSC with an expanded SSC range of up to
10,000 ppm in center-spread mode, support of up-, down-, and center-spread SSC
as well as new SATA ISI channel.
* Simplified setup for USB3 receiver stress test by simultaneous injection of
SSC and SJ from J-BERT N4903B.
