Product overview

SYN2303 The CDMA serial time server is a CDMA timing product designed and developed by Xi'an synchronous Electronic Technology Co., Ltd., which integrates CDMA receiver module. It can get UTC time information through CDMA network without card status. It can be deployed conveniently in any place where CDMA signals are available, especially suitable for deploying in the network communication room which is not convenient to deploy outdoor GPS/ Beidou antenna.In addition, because the CDMA antenna is conveniently placed indoors, it can completely eliminate the damage of lightning to the equipment.Using CDMA timing signal to synchronize the machine, generating serial port time information signal and 1PPS (second signal) synchronous pulse signal, it is a practical electronic instrument for establishing time scale and realizing time synchronization.

Key word CDMA clock, CDMA time service, CDMA time server.

Product function

1) CDMA timing signal is used to establish time reference.

1) Synchronously generate and output serial port time information, sending Beijing time information every minute, minute, second, year, month and day.

2) Output timing synchronization signal (1PPS), TTL interface output for testing;

3) LCD The clock surface (year, month, time, minute, second) shows.

4) WINDOWS Environment serial timing software.

Product characteristics

A) High cost performance and wide application.

B) The timing accuracy is high.

C) Fully guarantee data security, can set up the same network segment or different network segments.

D) Support a variety of popular time publishing protocols;

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

Typical application

1) Computer network, computer application system and process control management system;

2) The time unified system and all kinds of time display screens for power plant (station) and power grid center scheduling.

3) Electronic commerce system, B2B online system and database preservation and maintenance system;

4) Broadcasting, finance, mobile communications, petroleum, electricity, transportation, industry and national defense.

CDMA time service note:

1, the timing accuracy of CDMA timing device is better than 1ms, and GPS Beidou satellite signal is 30ns, so CDMA timing accuracy is low.

2, the time of CDMA timer is dependent on the time in the CDMA base station. If the time is wrong in the CDMA base station, the CDMA timer will also make mistakes. The manufacturer can only ensure that the output time of the CDMA timer is consistent with that of the CDMA base station.

3, CDMA timing device is easy to install, the equipment itself will bring a small pepper antenna, the length is about 5cm, as long as there is a place where the telecommunications signal can work properly.
