NTP/PTP IEEE1588 Modular Time Server

The NTS-5000 is a PTP/IEEE1588 grandmaster, NTP Stratum1 time server and ePRTC*, PRTC-A & B clock. It supports ref. time from GNSS or external atomic clocks. The std. version is equipped with Rubidium (Rb) and the LITE ver. supports  HQ OCXO holdover. The devices supports max. 10x LAN. The LAN1-2 are 100Mbps software timestamping, upgradable to 10GbE*. Optional 4x EXPANDER* cards are available, each supporting 2x 1GbE, with hardware timestamping. Network cards have own private PTP stack stored inside private FPGA. This approach ensures best cybersecurity and high stability of synchronisation. Product is suitable for any critical infrastructure and datacenter.
