The TSync-PCIe-PTP timing card adds support for precision time protocol (PTPv2 IEEE-1588) to the
popular TSync PCI Express timing card. It is a complete timecode reader/generator package for
servers and computers to realize sub-microsecond synchronization over the LAN. In slave mode,
the PCIe card is a PTP client as known as an “ordinary clock”. It synchronizes to a PTP master and
provides precision time-stamping functions to local applications as well as providing precision timing
signals to external devices. This provides an alternative to synchronizing with GPS antennas and
receivers when a precise network timing protocol is in place.
The TSync-PCIe-PTP can also operate in master mode when connected to a precision timing signal
such as IRIG timcode. In this case, the on-board precision oscillator is locked to the external reference
and is used to accurately synchronize PTP clients on the network. This function is well-suited for
facilities that are migrating from a dedicated timing infrastructure (such as IRIG over coaxial cable)
to one that leverages network infrastructure.
The card features all the other timing functions available from Spectracom’s TSync bus-level timing
platform. For example it offers industry-leading time-stamp accuracy with ±4 nanosecond resolution
and near zero-latency time reads. Time-stamping up to 4 different external events occurs at 5
nanosecond resolution at a rate up to 50 kHz. Additionally 4 programmable time match/frequency
outputs are provided. Other features include two unique timecode outputs, multiple programmable
square waves or “heartbeats”, multiple programmable “alarm” time match start/stop time outputs, a
10 MHz sine wave output, and 1PPS pulse output.

Key to the TSync functionality is the ability to generate interrupts. Using a Spectracom driver package
for the lastest version of Linux and Windows, you may congure your card using interrupt-driven
algorithms.
