Product Description:
Reliable and accurate synchronization is crucial for meeting the stringent requirements of key applications in multiple fields such as mobile operators, power utilities, and broadcasting. Network operators need a robust and scalable upgradeable solution to provide guaranteed phase, frequency, and time synchronization. However, achieving this goal in a cost-effective manner poses a challenge.
The T822 is a versatile and precise synchronization device designed to meet the strict frequency and phase synchronization requirements of new applications like 5G while also supporting traditional networks using IRIG, BITS, or NTP. It features a compact and flexible design optimized for deployment at the network edge, making cost-effective and precise synchronization solutions no longer a challenge.
Our T822 offers unique flexibility. It can be used as an IEEE1588v2 PTP master clock. With its NTP server and GNSS receiver functionality, including multiple sync fan-out options, our T822 is also well-suited for deployment in traditional synchronization architectures. To meet all installation requirements, we offer two ordering options: one with all connectors on the front and another with connectors on the back and a display on the front.
All these features make our T822 highly suitable for providing accurate and reliable time synchronization for both new and traditional solutions at the network edge.
