PTP master clock (time synchronization device) builds a computer network precision system
PTP clock synchronization can simultaneously receive Beidou satellite navigation system, GPS,
IRIG-B (DC) code, PTP network time Message and ground timing signal, generate pulse signal synchronized with UTC, IRIG-B time code, serial port time message, NTP/PTP network time message, to ensure the validity of time signal output and provide stable, reliable and accurate Time and frequency reference.
The PTP clock device is a carrier-class
IEEE1588-2008 master clock, providing high-performance client processing capabilities, hardware-based packet processing and redundant hardware architecture design, thereby achieving high scalability and maximum network availability . It combines the high-accuracy function of the IEEE 1588-2008 main clock, the high-performance output of the 10MHz/1PPS I/O port, and takes into account the compactness of the device (1U). It is very suitable for deployment in racks such as wireless telecommunication network controllers and base station controllers, where space is limited.
Dual-antenna dual-mode input design is adopted, based on the quality of the clock source signal or the priority level set by the user, it supports automatic switching between GPS/BD/IRIG-B/TOD/PPS signals to select the priority reference source. Support BMC algorithm, support 1+1 hot backup between servers, provide one server as the master, provide normal service, and another one as backup, so as to ensure that the client can still work normally when a failure occurs Influence. At the same time, the "dual power supply redundancy" mode can also provide excellent protection.
The PTP clock adopts a high-performance PowerPC+FPGA hardware platform, based on hardware time stamping and packet processing, and the embedded VxWorks real-time operating system provides high-performance client response capabilities. The PTP clock supports flexible and convenient software
parameter configuration for users. One can be selected
step/Twostep ,E2E/P2P,L3/L2,Unicast/Muiltcast settings ensure compatible interconnection in multi-client (Slave) provider application environment.
The PTP clock provides optional NTP service functionality, supporting a wide range of vendor products and protocols in existing mobile network base station locations. The PTP and NTP protocols can run at the same time respectively, and the two ETH time synchronization ports on the MCP board can be configured separately. The processing capacity of NTP requests can reach 40,000 times per second, while the carrying capacity of PTP can be maintained at up to 1,000 clients.
PTP clock modular design, multi-type standard interface input and output, constant temperature crystal oscillator or rubidium clock can be used at the same time, with high-precision self-timekeeping ability, so that service providers and network equipment manufacturers can choose the best based on network performance and application requirements maintain the level. It can carry out remote and local management through MNP1 and MNP2 network management, and supports viewing and exporting of logs.

Best Master Clock (BMC)
PTP is a nanosecond master clock for IEEE1588v2. Support five modes of PTP/NTP/GPS/Beidou/atomic clock. When using the internal GPS/Beidou as a reference clock,
the accuracy of tracking UTC is better than 100ns, and it can provide a time signal source of hundreds of nanoseconds through Ethernet.
In addition to using GPS as an external reference clock, rubidium atomic clocks, Beidou navigation satellite systems, high-stability constant temperature crystal oscillators (OCXO), etc. can also be used as reference clocks. At the same time, the clock can provide 1PPS-OUT and TOD-OUT standard output signals as well as IEEE1588v2-compliant PTP and other signals as clock sources for power and communication systems.
