Our IEEE 1588 PTP-Compliant Timing Solutions

Our IEEE 1588 Precision Time Protocol (PTP)-compliant timing solutions provide highly accurate frequency, phase and time synchronization, making them an excellent choice for use in 5G networks, data centers and other environments where precise timing is critical. Our portfolio includes a wide range of Phase-Locked Loop (PLL) devices, Precision Time Protocol (PTP) software and embedded Pulse Per Second (ePPS)/PPS distribution products, which help you meet the ITU-T G.8262.1, G.8273.2 (Class A, B, C, D) and G.8273.4 standards. Our multichannel devices support IEEE 1588 and Synchronous Ethernet (SyncE) timing requirements in compliance with the ITU-T G.8262 and G.8262.1 standards.

Five-Channel SyncE and IEEE 1588 Network Synchronizer

The ZL30735 is a comprehensive network synchronization solution featuring up to eight independent Digital PLLs (DPLLs) and five extremely low-output-jitter synthesizers, combined with IEEE 1588-2008 PTP stack and synchronization algorithm software packages. It serves as an excellent central timing solution for applications such as routers, switches, optical transparent networks and 4G/5G wireless base stations (CU/DU/RU).
