Vitesse Semiconductor Corporation and Microsemi Corporation 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 requirements.”

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.
