To help 5G mobile providers, cable operators and utility providers secure phase delivery, protection and synchronisation even when the GNSS is offline, jammed or spoofed, Microchip Technology has released software version 2.1 for its TimeProvider 4100 precision timing grandmaster.
TimeProvider 4100 is a 1588 grandmaster including support for the latest ITU-T G.8275.1 and G.8275.2 1588 phase profiles, complemented by extensive port fan-out for PTP, NTP, SyncE, and E1/T1. Software release 2.1 builds on previous versions by adding key software enhancements providing a vPRTC. Virtual PRTC gives the capability to create a redundant precise time distribution architecture for phase protection over an optical network.
Until recently, the principal source of precise time has been the GPS and regional constellations that include the GNSS. Deployment of GNSS, however, can be expensive for service providers given the costs connected with upgrading to GNSS-capable receivers and antennae as well as growing densification of end points. As a result, cable, telecom and utility operators deploying vPRTC benefit from solutions where GNSS dependency is decreased or eradicated.
TimeProvider4100 2.1 satisfies PRTC-B performance standards (per ITU-T G.8272) and supports 1G and 10G, NTP and PTP in a single form-factor system. The solution is available now for both new and already deployed systems.
