IEEE 1588-2008 and SyncE packet network support from Epson & Microsemi
Epson’s TG7050EAN TCXO provides short-term stability to support IEEE-1588 Precision Time Protocol (PTP) and Stratum3-compliant holdover for protection. It is claimed as being 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 comments, “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 intended for 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 synchronization with jitter performance of 0.25 psec RMS.
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 synchronization 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 synchronization integrated circuits (ICs).
