CISCO - Nexus High Precision Timestamping NIC

The Cisco Nexus High Resolution Timestamp Capture NIC is a 10Gbps, 0.25 nanosecond resolution network capture card that supports full line-rate capture with High Resolution Timestamps (HPT). It can synchronize the HPT clock with a PPS source such as a Grand Master and/or GPS receiver to within 1ns, and hardware assists Precision Time Protocol (PTP IEEE1588) packets for 2ns time synchronisation across machines.
