The SM2000 is a carrier-grade high-precision network synchronization device supporting IEEE 1588. It employs digital phase-locked loop technology and an independently developed timekeeping algorithm based on FPGA (Field-Programmable Gate Array) to provide high-precision, high-reliability time and frequency reference signals. This product has passed the certification of the Telecommunication Technology Labs (TTL) and has obtained network access licenses for Level 1 and Level 2 node clock devices issued by the Ministry of Industry and Information Technology (MIIT), enabling it to provide reference clock sources compliant with ITU-T G.811 and G.812 standards.

 In addition to providing the traditional 2Mbit/2MHz frequency synchronization signal, the SM2000 can also provide PPS+TOD, NTP, and PTP time outputs.
