PMC network interface card / XMC / Ethernet

Freescale QorIQ P1020 Processor-Based Conduction- or Air-Cooled XMC/PMC IEEE 1588v2 Grandmaster Clock Module
The XPort3200 is a rugged, IEEE 1588v2 Precision Time Protocol (PTP) ordinary clock with grandmaster capabilities. Hardware options range from commercial/air-cooled to full-military conduction-cooled solutions.
The XPort3200 is capable of providing nanosecond-level time and frequency synchronization for Ethernet networks. Support for multicast and optional unicast packets, along with grandmaster and slave operation, provide a complete IEEE 1588v2 solution.
1 PPS and input clock synchronization, as well as configurable clock and 1 PPS outputs, allow for synchronizing the grandmaster to an external time reference or providing a frequency reference to an external device.
