Agilent Technologies Inc. (NYSE: A) recently introduced
a new family of instrumentation-grade clock recovery solutions for optical and
electrical testing of high-speed digital communications components and systems.
The solutions offer the industry's highest bandwidth and low jitter performance
at significantly lower cost than similar products.
Bit-error-ratio testers and
oscilloscopes require a clock signal to synchronize the measurement system to
the incoming data stream. When the necessary synchronous clock is not
available, a common solution is to derive the clock from the data being
measured. Agilent's three new clock recovery products use this technique to
cover an extensive range of data rates and technologies.
The Agilent
N4877A clock recovery system provides instrumentation-grade
clock extraction for electrical signals for any rate from 50 Mb/s to 32 Gb/s.
The Agilent
N1070A combines the N4877A with the N1075A
optical coupler/converter to achieve optical clock recovery on
multimode signals to 16 Gb/s and single-mode signals to 32 Gb/s. The new clock
recovery products offer residual jitter performance as low as 100 femtoseconds
rms, which increases margin in jitter tests and minimizes degradation of
results by the test system.
Transceivers operating at 25 to 30 Gb/s
will be key components of next-generation communications systems, including
multilane devices for 100-Gb/s systems. Many test standards (for example, IEEE
802.3 Ethernet and Fibre Channel) require designers to use clock recovery for
test system synchronization. To achieve consistent results, key parameters
describing the jitter transfer and observed jitter transfer characteristics of
the clock recovery system are often specified. Agilent's new clock recovery
solutions provide this capability with an intuitive user interface, allowing
easy adjustment of loop peaking and loop bandwidth. The N4877A also provides
data demultiplexing to extend the range of bit-error-ratio test systems into
the 30-Gb/s range.
"Instrumentation-grade clock
recovery will be one of the essential tools for the design of next-generation,
high-speed digital communications systems and components," said Juergen
Beck, general manager of Agilent's Digital and Photonic Test Division.
"These new solutions will operate at the new industry-standard rates, but
also provide significant margin above those rates, giving engineers important
flexibility in their design and test strategies."
