Product overview
XQ-850 time synchronization system can receive Beidou satellite navigation system, GPS, IRIG-B (DC) code, PTP network time message and ground time service signal at the same time, generate pulse signal, IRIG-B time code, serial port time message, NTP / PTP network time message synchronized with UTC, ensure the effectiveness of time signal output, and provide stable, reliable and accurate time and frequency reference.
 
XQ-850 is the carrier level IEEE1588-2008 master clock, which provides high-performance client processing capability, hardware based packet processing and redundant hardware architecture design, so as to achieve high scalability and maximum network availability. It combines the high accuracy function of IEEE 1588-2008 master clock, the high performance output of 10MHz / 1PPS I / O port and the compact (1U) of the device. It is very suitable to be deployed in the field with limited space, such as wireless communication network controller and base station controller.

XQ-850 adopts dual antenna dual-mode input design. Based on the quality of clock source signal or the priority level set by users, XQ-850 supports automatic switching between GPS / BD / IRIG-B / TOD / PPS signals to select the priority reference source. Support BMC algorithm, support 1 + 1 hot backup between servers, provide one server for main use, provide normal service, and the other for standby, so as to ensure that when the failure occurs, the client can still work normally without being affected. At the same time, "dual power redundancy" mode can also provide excellent protection.
 
XQ-850 adopts high-performance PowerPC + FPGA hardware platform, based on hardware timestamp and package processing, and embedded VxWorks real-time operating system provides high-performance client response capability.


XQ-850 supports user's flexible and convenient configuration of software parameters. You can choose one step / twostep, E2E / P2P, L3 / L2, unicast / muiltcast settings to ensure compatible interconnection in the application environment of multi client (slave) suppliers.
 
XQ-850 provides optional NTP service functions, and supports many suppliers' products and protocols in existing mobile network base station locations. PTP and NTP protocols can run at the same time, and two eth time synchronization ports on MCP board can be configured separately. The processing capacity of NTP requests can reach 10000 times per second, while the carrying capacity of PTP can be maintained at up to 1000 clients.
