  Vitesse and Microsemi Ease Transition to IP Edge Networks

  Reference Design Delivers IEEE1588v2 Synchronization and Timing Technology
      Essential for Real-time Service Delivery in Packet-Based Networks

Business Wire

CAMARILLO, Calif. -- December 12, 2012

Vitesse Semiconductor Corporation (Nasdaq: VTSS) and Microsemi Corporation
(Nasdaq: MSCC) announced the availability of a joint reference design
delivering precise IEEE1588v2 (1588) timing and synchronization required by
carriers to deliver scalable, higher bandwidth communication services over
packet-based networks. Based on Vitesse’s Serval™ VSC7418 Carrier Ethernet
Switch Engine with VeriTime™ 1588 technology and Microsemi’s ZL30343
SyncE/IEEE1588 packet synchronizer (DPLL) and state-of-the-art clock recovery
algorithm, the reference design enables customers to leverage Vitesse and
Microsemi synchronization and timing expertise, and expedite time-to-market
with next-generation network products.

“Our jointly developed reference design allows broadband service providers to
simplify the implementation of 1588 synchronization and timing technology and
streamline the transition to IP Edge networks,” said Maamoun Seido, vice
president for timing products at Microsemi. “Demand for precise timing and
synchronization solutions is growing and we will continue to collaborate with
industry leaders such as Vitesse to deliver industry-standard 1588 solutions
to meet this need.”

“This reference design provides our customers with a proven path to add
precision timing needed for carrier access and backhaul networks,” said Uday
Mudoi, product marketing director at Vitesse. “Vitesse’s VeriTime portfolio
delivers nanosecond accurate time-stamping for both microwave and fiber
networks, which when combined with the Microsemi DPLL and clock recovery
algorithm, helps OEMs expedite upgrades to meet 4G/LTE network timing

Reference Design Details

The reference design, known as the VSC5619EV, is available immediately. The
embedded processor in the Serval device runs Vitesse CEService software,
combined with Microsemi’s clock recovery algorithm.

The reference design meets the performance demands for timing synchronization
in accordance with ITU-T Recommendation G.8262/G.8261 for wireless base
stations, radio network controllers, gateways, aggregation and transmission
equipment, and routers while reducing design complexity. Additional details
are available at Contact your local
Vitesse sales office to learn more.

Specific devices on the VSC5619EV include:

  *Vitesse’s VSC7418 Carrier Ethernet Switch Engine is part of its
    industry-leading VeriTime portfolio of 1 Gigabit Ethernet (GE), 10GE, 10GE
    OTN PHYs and Carrier Ethernet switch engines. For more details, visit
  *Microsemi’s ZL30343 SyncE and IEEE 1588 packet synchronizer, part of the
    ZL3034x family of DPLLs, which provide all required clock synthesis and
    network timing functions for a central timing card or line card in carrier
    grade network equipment. The ZL3034x chipset is based upon proven G.813
    EEC Stratum3 timing silicon for clock synthesis, with additional support
    for IEEE 1588-2008 (PTP) and Synchronous Ethernet (SyncE) timing
    references. For more details, visit
