PTP/NTP master clock synchronization

Production Introduction

LX-500C multi-function time synchronization box is suitable for time synchronization of base stations, automatic driving, rail transit, scientific research and military industry, electric power, etc. It can simultaneously receive Beidou satellite navigation system, GPS, PTP network time messages and PPS_TOD, IRIG-B (DC ) code and other ground timing signals to generate PPS signals, IRIG-B time codes, PPS_TOD time messages, and NTP/PTP network time messages that are synchronized with UTC to ensure the validity of time signal output and provide stable, reliable and accurate time and frequency reference.

The LX-500C provides high-performance client processing capabilities and hardware  architecture design based on hardware timestamps to achieve high scalability and    maximize network availability. It combines the high-precision function of IEEE 1588-2008  Grandmaster and NTP function,and 10MHz/1PPS/IRIG-B/PPS_ TOD etc. The compactness of the equipment is suitable for autonomous vehicle, base station controllers and other racks in narrow spaces.

The LX-500C adopts a dual-mode input design. Based on the quality of the clock source signal or the priority level set by the user, the LX-500C supports automatic switching between GPS/BD/PTP/NTP/IRIG-B/PPS_TOD signals to select Preferred reference source. Support BMC algorithm, support 1+1 hot backup between servers, provide one server as the main function to provide normal services, and the other as a backup, so as to ensure that when a fault occurs, the client can still work normally.

LX-500C supports user's flexible and convenient software parameter configuration. One step/Two step, E2E/P2P, L3/L2, Unicast/Muiltcast settings can be selected through WEB operation, which ensures the application environment of multiple client (Slave) suppliers. Compatible interconnection is still possible.

LX-500C supports the input and output of multiple types of standard time interfaces. At the same time, it has a built-in RTC module, supports the time retention function after power off and starts, and supports the manual setting of the time forced output function. LX-500C can be managed locally through WEB.
