Introduction of SYN4632 PCIe clock synchronization

Product overview

SYN4632 The PCIe clock synchronization card is a synchronous card developed by Xi'an synchronous Electronic Technology Co., Ltd., which provides high precision hardware clock for computers, industrial computers and other operating systems through PCIe bus. The clock synchronization card is produced by pipeline automation patch production. The FPGA+ARM frame is used to design the external reference signals such as GPS/ Beidou /PTP/, AC and DC IRIG-B code /CDMA/1PPS/10MHz, etc., and output various time and frequency signals, so as to improve the time accuracy and accuracy of the system and meet the needs of different users.

The clock synchronization card has a high precision time keeping clock source and can provide high precision time service when the external reference is invalid. It also provides Windows timing management software and API drivers of all kinds of operating systems. It fully realizes the timing of high precision application programs, and has the characteristics of strong compatibility, rich interface, high accuracy, good stability, strong function, no accumulation error, no environmental restrictions such as regional climate, high cost performance, simple operation and maintenance free. PCIe clock synchronization card

Product function

A)   PCIe bus timing is supported, and time accuracy is better than 10us.

B)   Built in high precision timing GPS/BD dual mode receiver;

C)   The external reference is time locked by the built-in high precision clock after losing the lock.

D)   Support Plug and Play.

E)   Output second pulse (PPS) time scale synchronous pulse signal;

F)   Windows/Linux Drive to provide API function interface;

G)   Windows upper computer timing software is provided to automatically calibrate the computer.

H)   A variety of interrupt signals can be provided on the PCIe bus.

I)   PCIe The bus provides information such as time information, GPS, BD satellite number, and card synchronization status.

J)   Output 1PPS and serial port TOD (NEMA0183 GPRMC statement, with latitude and longitude positioning information).

Product characteristics

A)   High precision, fully automatic, unattended and maintenance free.

B)   The main circuit part is shielded with metal shell, which has strong anti-interference ability.

C)   With low power consumption and high reliability, it can work steadily for a long time.

D)   Easy installation: the product can be directly inserted into the PCIe expansion slot of the computer (or IPC).
