Xi'an SYNC

Product overview

The SYN2407E IEEE1588 master clock module is a PTP precise timing master module developed by Xi'an synchronously.The PTP master clock module can be used as a set of precise time synchronization system with PTP slave devices and ordinary switches. The master slave clock mode does not need special 1588 switches to encode the time information, and the master slave time frequency phase synchronization is realized by using the symmetry and delay measurement technology of the network.In the synchronization process of the system, this module receives external input 1PPS+TOD clock reference source, outputs IEEE STD 1588V2 synchronization protocol externally, and has nanosecond time transmission accuracy.

The PTP master clock module outputs external IEEE1588 network precision time protocol, and the built-in high precision temperature compensation crystal oscillator can also receive external reference clock signals. The synchronization accuracy can reach 30 nanoseconds (RMS).Users do not need to know the specific protocol of IEEE STD 1588V2. The software and hardware of the module are designed in a neutral way, which is easy to be embedded into the user equipment and realize PTP high precision time service. It is a PTP master clock module with convenient operation, low cost and high integration.

Product function

1) the corresponding parameters can be configured flexibly by serial port or network port or UDP.

2) accept external serial port time information and 1PPS time reference signal;

3) the WEB interface is designed with neutral design to facilitate integration.

4) support P2P and E2E mode;

5) support the standard PTPv2, that is, IEEE STD 1588V2-2008 network time protocol, and support HTTP/UDP.

Product characteristics

A) has the function of issuing instructions to dynamically compensate 1PPS accuracy.

B) has the function of searching IP and configuring network parameters through UDP network.

C) has the function of WEB page configuration and preservation of PTP network parameters.

D) single power DC5V power supply, low power consumption;

E) the application circuit is simple, no peripheral auxiliary circuit, and the module has its own network transformer. It only needs to provide DC5V power supply and ordinary network interface to use.

Typical application

1) mobile base station, smart grid time synchronization, CMMB base station, digital TV digital broadcasting;

2) time synchronization of Internet of things, synchronization of industrial automation and synchronous acquisition of signals.
