MULTIsync IP Core is a multi-protocol redundant time synchronization core that provides sub-microsecond time synchronization, providing maximum flexibility for every scenario. It is able to provide time synchronization using IEEE 1588-2006 (PTPv2) and IRIG-B time synchronization protocols. 

MULTIsync IP Core supports the following synchronization input sources:

  • PTP: Ethernet. PTP Slave at the input
  • IRIG-B: IRIG-B compliant signal. IRIG-B Slave at the input
  • Free Running Timer: Digital input

MULTIsync IP Core supports the following synchronization output options:

  • PTP: Ethernet. PTP master at the output
  • IRIG-B: IRIG-B compliant signal. IRIG-B Slave at the output
  • Free Running Timer: Digital Output

This versatility enables different cases-of-use for MULTIsync that are complementary:

  • It can provide time synchronization redundancy, making possible to connect the IP to a PTP network and to an IRIG-B master at the same time. The user is able to select which is the time source used between the three available ones (PTP, IRIG-B, free running timer)
  • It can act as a PTP to IRIG-B or IRIG-B to PTP bridge while the IP is synchronized with the selected master
  • It can act a PTP or IRIG-B grandmaster

MULTIsync can be used in combination with SoC-e HSR-PRPSwitch, TSNSwitch, UnmanagedEthernetSwitch or ManagedEthernetSwitch IP cores to introduce Ethernet traffic switching capabilities or HSR and PRP redundancy.

MULTIsync is supported on the following Xilinx FPGA Families:

  • 6-Series (Spartan, Virtex)
  • 7-Series (Zynq, Spartan, Artix, Kintex, Virtex)
  • Ultrascale (Kintex, Virtex)
  • Ultrascale+ (Zynq MPSoC, Kintex, Virtex)

MULTIsync is designed to be easily integrated in your FPGA designs by taking advantage of the new Xilinx Vivado Tool, that allows to use the IP Cores in a graphical user interface and configure IP parameters in an easy way.

MULTIsync IP Core main features:

  • Multi-protocol redundant time synchronization.
  • IEEE 1588-2006 (PTPv2) and IRIG-B time synchronization protocols supported simultaneously.
