Silicom’s P425G8TS81 TimeSync Card STS3 25/10 Gigabit Ethernet PCI Express Grand Master TimeSync server adapter adds TimeSync/GM ability to server /mobile DU systems.

The Silicom P425G8TS81 TimeSync Card STS3 NIC is based on Intel E810 NIC controllers and Microchip / servo PLL.

Silicom’s STS3 Support 8 port of 25G/10G capabilities to synchronize host system with external clock source using 1PPS and 10MHz. The STS3 TimeSync server adapter support both 1588v2/PTP and SyncE for high clock accuracy in Master and Slave mode. STS3 design is meeting O-RAN requirements for LLS-C1, LLS-C2 and LLS-C3, modes of operations with both Boundary and Transparent clocks.

Silicom STS line card for 4G and 5G NIC enable real-time data transmission with high timing accuracy at the lowest cost to power 5G DRAN and CRAN edge deployments:
