Semtech Corporation recently announced the successful deployment of its ToPSync platform in more than one million network elements. Currently more than 100 carrier networks deploy ToPSync devices. The ToPSync platform has been designed to address challenges presented by 4G time-aligned technologies amidst advancements in small cell technology, which is critical for delivering high quality mobile broadband.


In a statement, Rich Lansdowne, managing director of Semtech’s Timing and Synchronization business, said, “We started to get involved with PTP almost 10 years ago. To see this technology ‘come of age’ now is really exciting; everyone is talking about it. We have a great roadmap of new firmware and devices committed to lowering the cost, size, and power while increasing flexibility and performance. In fact, our newest devices and firmware can support 100ns time alignment for small cells with a $5 TCXO.”

Some of the key features of the ToPSync include comprehensive support for all modes of IEEE1588: multicast/unicast, one-step/two-step, I.P/Ethernet; one chip for all master, slave and boundary clock applications; firmware that is patented for technique used for eliminating wander accumulation in boundary clock chains; and robust SONET/SDH/SyncE SETS solution (G.812/813, G.8262, GR253, GR1244, etc.).

Development of next-generation wireless networks such as TDD- LTE (News - Alert) advanced services are subject to delivery of time alignment to base stations. The PTP solution from Semtech ensures the delivery of required performance that is meshed with a high degree of reliability. By integrating embedded SONET/SDH & SyncE solution with the CPU, algorithm, and the required time-stamping, multistandard performance has been optimized.  

Other innovative features include a unique hybrid solution that integrates any layer 1 recovered clock with PTP for delivering optimized time alignment performance; established performance which is an improvement over 300ns with OCXO on 10-switch G.8261 stack through all test case conditions; and complete hybrid performance which is an improvement over 100ns with TCXO on 10-switch G.8261 stack spanning all test case conditions.
