1INTRODUCTION
The Silicom PE10G8TS81 TimeSync Adapter STS2 is a 1/10 Gigabit Ethernet PCI Express Gen4
TimeSync server adapter, designed for X86 Servers and high-end appliances.
The 1/10 Gigabit Ethernet TimeSync PCIe server adapter is based on the Intel E810 chipset and best in
the industry timing solution targeting 5G/Class C wireless base stations and carrier-grade systems.
The Silicom STS2 provides support to synchronize the host system from any of the eight 1G/10G ports
or from an external 1PPS or 10MHz. The STS2 TimeSync server adapter supports both 1588v2/PTP
and SyncE for high clock accuracy in PTP Master and PTP Slave modes. The design conforms with O-
RAN requirements for LLS-C1, LLS-C2 and LLS-C3 (O-RAN-WG4-CUS.0-v04.00) operation modes
with both Boundary and Transparent clocks.
The Silicom STS2 supports:
•IEEE1588v2/PTP over IPv4, IPV6, and Ethernet
•PTP profiles ITU-T G.8275.1 and ITU-T G.8275.2
•SyncE /ITU-T G.8262
•T-BC Boundary Clock and T-TSC Slave Clock / ITU-T G.8273.2
•T-GM Grand Master /G.8273.1
•PRTC Primary Reference Time Clock Class B/G.8272
•T-TC Transparent Clock /G.8273.3
•1588 Software Stack and Servo Software in x86

4. Push the card downwards into the slot. Apply moderate pressure until the card “clicks” into
place and sits snugly in the slot.
5. Ensure the card connectors align with the slot’s back panel aperture and secure the card with
a screw.
