IEEE 1588v2/PTP Grandmaster for clock and time sync to multiple slaves via Ethernet

X-ES launches XPort3200, an IEEE 1588v2/Precision Time Protocol (PTP) Grandmaster designed to provide clocking and time synchronization to multiple slaves via Ethernet.

The XPort3200 is suggested for use in industrial applications such as assembly lines and printing presses to military applications such as multi-sensor data time-stamping, control system synchronization, and telemetry.

IEEE 1588 uses a standard Ethernet network to transfer clock and time information, providing accurate nanosecond-level synchronization with minimal software overhead and without introducing a secondary method of communication to slaves.

XPort3200 is designed using Freescale Semiconductor's QorIQ P1020 processor to perform the IEEE 1588 time-stamping. Hardware time stamping feature in P1020 processor provides accurate egress and ingress timestamp with a resolution of 8 ns. External GPIO time stamp pins in P1020 processor includes can be used to synchronize the XPort3200 to a Pulse Per Second (PPS) input to provide accurate clock synchronization.

In case of requirement of a absolute time reference in some of the applications, XPort3200 provides time reference from a serial port or a GPS receiver. If no external time reference is available, the XPort3200 features a Stratum 3-compliant, oven-controlled oscillator to provide IEEE 1588 slaves an accurate time reference.

The XChange3013, XChange3018, and XChange3100 VPX Ethernet switches can host the XPort3200, and all three switch products feature transparent IEEE 1588 clocking that ensures accurate synchronization to all devices connected to the switch. This allows very accurate distribution of the XPort3200 IEEE 1588 time to many different slaves. The XPort3200 can be supplied as an XMC or PMC with P14 or P16 I/O connectors, allowing for installation in nearly any mezzanine site, says X-ES.
