Xi'an SYNC

Product overview

The SYN4901 type high precision time and frequency transfer equipment is a long distance time frequency optical fiber transmission equipment designed and developed by Xi'an synchronous Electronic Technology Co., Ltd., which is equipped with high-precision constant temperature crystal oscillator 0CXO or rubidium atomic clock. It receives external clock signals such as Beidou two generation /GPS/GLONASS satellite signal, dedicated optical fiber signal, IRIG-B code, E1 and so on, outputs special clock signals such as optical fiber clock signals and PTP/NTP/E1/ AC and DC IRIG-B/TOD/1PPS/1PPM/10MHz.

Through the cascade expansion, the transfer device realizes multi-level chain, star and mesh transmission network, and facilitates users to build high precision time service system for ground-based optical fiber.

Product function

1) the external reference input signals include one satellite signal, dedicated optical fiber signal and IRIG-B (DC) signal.

2) satellite selection function: there are six choices: GPS Beidou mixed time service, GPS&GLONASS mixed time service, Beidou GLONASS mixed time service, single GPS time service, single Beidou time service, single GLONASS time service to meet customer's demand for satellite signal timing.

3) work mode: including automatic mode, manual mode, punctual mode and so on three modes, in which the automatic mode indicates the priority selection of satellite signals, and then selects the IRIG-B signal; manual mode indicates that the external reference is manually selected by the user; the time keeping mode indicates that the external reference is not received, and the internal oscillator is used to carry out the time keeping;

4) system setup function: users set up baud rate, time zone and delay by pressing key.

5) automatically save various configuration states to meet all kinds of customer needs.

Product characteristics

A) has high cost performance, wide application and high time service accuracy.

B) a variety of timing interface output, which can be freely assembled and can output 120 groups of time service interfaces at the same time.

C) the overall power consumption is small, using no fan design, reliable and stable operation.

Typical application

1) mobile base station and ground high precision time transfer network.
