GS5210 Clock Management Device - Grandmaster Clock
Products Introduction
The GS5210 clock management device is a comprehensive time management system with all-around performance. It features a built-in high-performance synchronized clock source (crystal oscillator/rubidium clock selectable), supports multiple frequency standards input, multiple 1PPS+TOD channels and multiple B(DC) code inputs, enabling clock group management, time synchronization, frequency synchronization, and other functions.
It delivers a wide range of time signal outputs - including 10MHz/10.23MHz/100MHz, 1PPS+TOD, B(DC), and E1 - and can serve as an NTP and PTP grandmaster clock. The device also features an intelligent multi-channel atomic clock frequency standard management algorithm with high-precision frequency and phase adjustment.
Its high integration, modularity, and superior performance maximize the fulfillment of users' time management needs.
