NetTimeLogic’s NTP Server is a full hardware (FPGA) only implementation of an SNTPv4 Server according to RFC 4330/5905. It supports hardware timestamping and insertion with 4ns resolution and responds to NTP requests from NTP clients fully in hardware, which gives an unprecedented performance of 100k+ requests/s (~900k@1G) with minimal resource usage. It supports the NTP unicast, multicast, and broadcast mode (IPv4/IPv6) and converts from TAI to UTC (taking leap seconds and smearing into account).
