Seiko Epson Corporation, a leader in quartz crystal technology, and Microsemi Corporation, a leading provider of semiconductor solutions differentiated by power, security, reliability and performance, has announced their joint development of compliant network synchronisation solutions, with Epson’s TG7050EAN high frequency high stability temperature compensated crystal oscillator (TCXO) supporting Microsemi’s ZL30722 IEEE-1588 and Synchronous Ethernet (SyncE) packet Eclock network synchroniser.
Epson’s TG7050EAN TCXO provides short-term stability to support IEEE-1588 Precision Time Protocol (PTP) and Stratum3-compliant holdover for protection. It is unique in offering both high frequency and high stability, with margin to industry maximum time interval error (MTIE) and time deviation (TDEV) specifications to ensure reliable operation under real-world conditions such as rapid airflow and temperature changes.
‘Epson is committed to developing network synchronisation solutions,’ said Masayuki Kitamura, chief operating officer of Epson’s microdevices operations division. ‘The superior wander characteristics of our TG7050EAN enable dependable IEEE-1588 synchronization in congested networks. Working with Microsemi allows us to solve synchronization problems for the latest packet networks, including small cells and mobile backhaul.’
Microsemi’s ZL30722 is ideal for a wide range of applications, including small cell routers and switches, broadband access, carrier Ethernet equipment and wireless equipment such as base stations and backhaul equipment, as well as smart grids and synchrophasors. The device provides SyncE/IEEE-1588 synchronisation with excellent jitter performance of 0.25 pico seconds (ps) root mean square (rms).
‘As our customers rely on our deep expertise in timing and synchronisation to provide proven, standards–compliant timing solutions, working with a company like Epson brings great value to Microsemi, as it enables us to offer a complete IEEE-1588 and SyncE–compliant solution and further enhances our diverse product offerings,’ said Maamoun Seido, vice president and business unit manager of Microsemi’s timing products. ‘This collaboration not only helps provide our customers with standards-compliance assurance, but it also allows them to create a dependable solution for real-world network conditions.’
Together the TG7050EAN and ZL30722 comply with ITU–T G.813, G.823, G.824, G.8261, G.8262 and G.8263, providing the frequency accuracy and phase synchronisation required by multiple wireless and wireline protocols and supporting new ITU-T packet clock drafts and recommendations. The TG7050EAN is now sampling and joins Epson’s TG-5500 TCXO and other Epson timing devices qualified for use with Microsemi’s family of synchronisation integrated circuits (ICs).
