PE425G4TSi81L TimeSync Card STS1

25Gigabit Ethernet TimeSync PCI Express Gen4 Server Adapter

Silicom’s Time Sync (STS1) PE425G4TSi81L is a 25 Gigabit Ethernet PCI Express Gen4 TimeSync server adapter, designed for X86 Servers and high-end appliances.
The 25 Gigabit Ethernet TimeSync PCIe server adapter is based on Intel E810 chipset and best in the industry timing solution targeting 5G/ Class C wireless base station and carrier-grade systems.

Silicom’s STS1 Support 4 port of 10G/25G capabilities to synchronize host system with external clock source using 1PPS and 10MHz. The STS1 TimeSync server adapter support both 1588v2/PTP and SyncE for high clock accuracy in Master and Slave mode. STS1 design is meeting O-RAN requirements for LLS-C1, LLS-C2 and LLS-C3, modes of operations with both Boundary and Transparent clocks.
