IEEE1588 Chips


 IEEE 1588 Precision Time Protocol (PTP) is a packet-based two-way communications protocol specifically designed to precisely synchronize distributed clocks to nanosecond resolution, typically on an Ethernet or IP-based network.Combined with physical layer technologies such as SyncE, IEEE 1588 can provide  more accurate time calibration. Dapu offers the industry’s most comprehensive and single Chip of IEEE 1588 solution with a range of products.
