NetTimeLogic’s NTP Server is a full hardware (FPGA) only implementation of a SNTPv4 Server according to RFC 4330/5905. It supports hardware timestamping and insertion with 4ns resolution and repondes to NTP requests from NTP clients fully in hardware which gives an unprecedented performance of 100k+ requests/s (~500k) with minimal resource usage. It supports the NTP unicast, multicast and broadcast mode and can forward non-§NTP frames for sharing the same Ethernet port with e.g. a CPU. Conversion from TAI to UTC (taking leap seconds and smearing into account) is completely done in HW. This allows running NTP synchronization completely independent and standalone from the user application. The core can be configured either by signals or by an AXI4Light-Slave Register interface.
All calculations and corrections are implemented completely in HW.
