General Information
The eurocard TSU-V2 acts as a standalone single board computer including network
interface card (10/100MBit) with integrated Time Stamp Unit for obtaining time
stamps in IEEE1588 (PTPv2) compatible networks. In conjunction with a single
board computer and a reference time source (PTP master only) the module is capable
of building a PTP Master or Slave system:
The Time Stamp Unit, integrated in a FPGA ( F ield P rogrammable G ate A rray,
programmable logic device), checks the data traffic on the MII-interface between the
PHY receiver (physical connection to the network) and the Ethernet controller (MAC)
of the module TSU-V2. If a valid PTP packet is detected, the Time Stamp Unit takes
a time stamp that is read out by a micro controller and passed to the single board
computer (SBC) running the PTP driver software.
