PTP/NTP master clock synchronization

Product Overview:

LX-10 is a high-performance time server designed in China, with complete timing interfaces and numerous management interfaces, which can meet the timing requirements of large data centers. The device has good scalability and strong adaptability. It can be expanded to multiple time sources, and the hardware supports two time sources, BDS and GPS, and can also use handheld satellite receivers for timing.

According to the characteristics of large data centers, it can support ultra-long satellite antenna cables, rubidium atomic clocks for timekeeping, or regular handheld timing.

The device has a wealth of management interfaces, which is convenient for operation and maintenance, and can know the time synchronization status of clients in the network.

Main applications:

Enterprises, universities, hospitals, finance, data centers, Internet cloud computing, etc.

Main features:

• Receives BeiDou/GPS satellite system signals as a primary time server

  
  

• Can operate as a secondary time server

• Supports NTP MD5 authentication, unicast, broadcast, and other modes

• Two Gigabit adaptive Ethernet ports, supporting bonding

• Time response capacity: >5000 requests per second

• Built-in oven-controlled crystal oscillator (OCXO), maintaining high time accuracy when external time sources fail

• Supports HTTP and web-based login for management

• Supports management software to view and download client synchronization status

• Supports management software to view and download client synchronization status

  
  

• Can receive satellite time sources and generate pulse signals synchronized with UTC, NTP network time packets, etc., ensuring the validity of time signal output and providing a stable, reliable, and accurate time reference.

• It adopts a multi-mode satellite receiver and supports 1-channel GNSS input (BeiDou/GPS satellite time source), or it can operate as a secondary time server.。

• It offers high cost performance and is particularly suitable for deployment in small computer networks, such as time synchronization for cameras in video surveillance systems, and time display systems in airports, railway stations, stadiums, schools, hospitals, and government institutions.

  
  

• Can handle up to 5000 NTP requests per second. The two Gigabit Ethernet ports can be configured separately or used as a bonded port.

• It is equipped with an OLED display and LED status indicators to show clock operating status. Users can configure and manage the system via a web interface, offering flexible configuration options such as network IP parameter settings, status monitoring, remote access, control, log viewing, and NTP client information viewing and export, enabling efficient management and maintenance and greatly improving flexibility and convenience.

• It uses an internal oven-controlled crystal oscillator. In addition to using GNSS as an external reference clock, it can also use the OCXO as a reference clock. It also features an internal disciplining and holdover algorithm, providing high-precision autonomous timekeeping capability.

Main Advantages:

• High cost-performance ratio

• NTP time synchronization accuracy better than 50 μs

• Supports up to 10,000 NTP clients

• Security: whitelist and blacklist mechanisms

Main Applications:

• Video surveillance

• Mining

• Airports and railway stations

• Stadiums, schools, hospitals, government institutions
