Supported Features

The Spectracom TSync PCIe board supports multiple prioritized timing inputs. When an input is lost, the unit automatically switches to the next input in order of priority.
The disciplined onboard oscillator is phase-locked to an external timing input, providing 5ns resolution time. This 10 MHz oscillator, central to the TSync-PCIe timing functions, uses the last known reference to increment ("freewheel") in the absence of a timing input.
IEEE-1588 (PTP – Precision Time Protocol) can be used to synchronize multiple systems over Ethernet. The Spectracom driver can act as an IEEE-1588 slave or master. FPGA clocks can be hardware synchronized by the Spectracom card when using a “Clock Adapter” board.
