Vitesse Semiconductor has accumulated multiple design wins with nine of the market-share leaders in the IP Edge microwave/millimeter-wave backhaul networking equipment space. These OEM customers account for almost 60 percent market share in the microwave backhaul and 75 percent in the millimeter-wave backhaul segments. These wins leverage Vitesse’s technology with VeriTime, its patent-pending distributed timing technology, with the industry’s highest-accuracy IEEE1588v2 timing for IP Edge networks.
“Design wins are a leading indicator of Vitesse’s market-share growth in the target markets,” Uday Mudoi, director of product marketing at Vitesse, told Backhaul Bulletin. “They represent new customer designs started within the stated period, using our devices. As these designs reach production, it will translate to Vitesse revenue and market share. This is a clear indication of OEM acceptance of Vitesse’s solutions and technology. Beyond translation to direct revenue for current devices, many of the wins are customer affirmation of our roadmap devices in development.”
Customers are choosing Vitesse as a strategic technology provider, not for specific devices, according to Mudoi. He continued to tell the Bulletin that one of most important implications for their customers is how they can leverage their design and testing effort, including hardware, software and system-level qualification, across their products and for multiple generations.
VeriTime represents fifth-generation IEEE1588v2 IP and has been validated by several major OEMs in real-world tests. The company’s recent presentation of performance results to the ITU-T documented VeriTime’s better than 3 ns per node accuracy over a nine-node IEEE1588v2 transparent clock (TC) network chain and superior long-term phase stability, making it the solution that fulfills TD-LTE and LTE-Advanced (LTE-A) requirements in real-world tests today.
According to Mudoi, TD-LTE/LTE-A deployments require much more stringent timing synchronization than current networks. Sub-10 nanosecond timing accuracy is required for these mobile networks to be truly mobile. “Without it, users suffer data corruption, dropped calls, slow handover between cells, co-channel interference, speech clipping, while networks suffer increased latency, requiring buffering to “align time. VeriTime offers accuracy to meet LTE-A deployment requirements today,” Mudoi told the Bulletin.
“Timing accuracy requirements for 4G/LTE-A/TD-LTE are at least six times more stringent than for 3G,” said Pat Diamond, timing industry veteran and pioneering member of the IEEE1588-2008 PTP Working Group, of Diamond Consulting, in a company release. “Clearly, network equipment OEMs recognize this fact. Given the rigorous level of timing accuracy for LTE networks simply to function, solutions like Vitesse’s VeriTime enable OEMs to future-proof their equipment for tomorrow’s wireless backhaul networks.”
