Zarlink and Marvell(R) First to Demonstrate Synchronous Ethernet Solution Supporting Network-Quality Performance

    - Companies demonstrate synchronization over Ethernet physical layer
      using Zarlink PLL (phase locked-loop) and Marvell Ethernet PHY

    OTTAWA, Jan. 31 /CNW Telbec/ - Zarlink Semiconductor (NYSE/TSX:ZL) and
Marvell(R) (NASDAQ:  MRVL) today announced the successful demonstration of a
synchronous Ethernet solution using already available products from both
companies that will allow carriers to support real-time services over
packet-based networks.
    Carriers face a major stumbling block in the drive towards network
convergence because many applications with "built-in" timing requirements rely
significantly on network synchronization. For example, economical cellular
backhaul over IP networks requires synchronization to allow legacy
applications such as voice and fax to function properly. As high-growth
applications such as YouTube and AOL Video gain popularity, these applications
need to co-exist alongside critical time-sensitive services on IP backhaul
networks. To guarantee performance, carriers must currently operate a number
of different networks and deploy costly external mechanisms to ensure
    In response, Zarlink and Marvell's collaborative solution focuses on
emerging synchronous Ethernet solutions that allow carriers to support
real-time services over asynchronous Ethernet networks. In synchronous
Ethernet operation, each piece of network equipment must have synchronized
timing capabilities.
    To meet this requirement, the companies have successfully completed
interoperability testing demonstrating that Zarlink's ZL(TM)30120
analog/digital PLL can synchronize a Marvell 88E1145 Ethernet physical layer
device to a telecom networking timing reference, while generating a very low
jitter (picoseconds) Ethernet clock. This will enable developers of Ethernet
switching and routing platforms to provide complete end-to-end solutions for
next-generation IP networks.
    "This interoperability testing advances Marvell's commitment to deliver
the most comprehensive and technologically advanced Ethernet PHY solutions for
the carrier market," said Ozdal Barkan, director of PHY Technology for the
Connectivity Business Unit, Communications and Consumer Business Group at
    "As IP networks become ubiquitous, the ability to accurately synchronize
what is by design a best-effort infrastructure is just as critical as the data
that is being carried across the network," said Mel Roberts, director of
Business Development, Zarlink Semiconductor. "By combining best-in-class
technologies from the two companies, we will be able to provide customers with
unique synchronous Ethernet solutions that offer network quality
