overview

MEGA6626C industrial grade IEEE 1588 synchronous clock source is a precision clock server that supports hardware timestamp based IEEE1588v2, supports BC, P2P TC, E2E TC clock modes, and achieves 50ns timing accuracy. When using GPS as a clock reference source, the accuracy of MEGA6626C tracking UTC is better than 20ns, and high-precision time signal sources can be provided through Ethernet. The MEGA6626C synchronous clock source uses professional processing chips to provide clock references for multiple slave clocks simultaneously. In addition to using GPS as an external reference clock, the MEGA6626C synchronous clock source can also use the BeiDou Navigation Satellite System. In addition, the MEGA6626C synchronous clock source also has one GPS module (one GPRMC time information input, one PPS second pulse input), which obtains nanosecond level time accuracy through Ethernet. Compared to standalone clock synchronization systems, it can reduce the cost of the entire time synchronization system and achieve higher cost-effectiveness.MEGA6626C synchronous clock source is used in industrial automation systems, aerospace systems, 2.5G/3G/4G base stations, digital substations, CMMB base stations, digital television and broadcasting, telecommunications rooms and other places that require precision clock services.
