P60 Gateway Clock
Emerging applications in 4G, LTE-Advanced Infrastructure, 5G, and the migration of transmission and distribution substations towards the smart grid have been fueling the need for higher precision time synchronization. Qulsar’s Managed Timing Engine (MTE) board P60, is a best of breed solution for network equipment vendors looking to implement a time synchronization system using IEEE1588 PTP packet timing to deliver a full, high performance, robust timing solution.
The P60 can operate as either a PTP ordinary clock in either master or slave mode, or as a gateway clock, in which it functions as a PTP boundary clock while also optionally accepting a time-of-day input from a GNSS receiver to allow multiple sources of time to be used simultaneously.
Design & Integration
The P60 board enables a simple path to quickly integrate a precision synchronization system into a host system.
The P60 can be integrated as a slave into an end-point where precision timing signals are required such as macro, micro or pico small cells (eNodeBs) in telecom applications and into Intelligent Electronic Devices (IEDs), and protection relay devices for the modernization of substations in power utility smart grids. It can also be integrated into systems that need to provide Grandmaster functionality such as Time Servers and Edgemaster clocks.
The P60 has two Ethernet interfaces - one a 1000Base-T RJ-45 and the other an SFP socket supporting gigabit optical or copper SFP modules. A 40-pin header allows connection to a host system. The P60 systems provide ‘wire speed pass through’ functionality which makes the P60 fully transparent to the network and the host system.
The P60 can directly connect to a GPS receiver that provides a 1PPS and time-of-day (ToD) signal and distribute timing to downstream slave devices via PTP. It can also receive timing over PTP and output this locally while simultaneously acting as a PTP boundary clock. Local timing outputs consist of a syntonized frequency at 5, 10, 20 or 25 MHz, a phase-aligned 1PPS and a ToD serial stream in NMEA, ASCII or ‘China Mobile’ format.
One of the innovative features of the P60 is that it can be integrated into an existing communication path. It features a low latency, fully transparent data communication channel at gigabit speed, allowing for daisy chaining architectures.
Advanced Time Recovery Algorithms
The P60 has industry leading algorithms that enable it to extract precise time from a remote master over a real-world network in which the timing packets experience packet delay variation (PDV) caused by multiple switches handling interacting traffic flows.
In addition, the P60 has cutting-edge patented technology that allows simultaneous operation with both PTP and a local GNSS-based source of time. The ability to use multiple synchronization inputs is particularly powerful in today’s applications, where a host system may need to be versatile and deployable in diverse environments.
