User Guide
1.0 Introduction
Although IEEE 1588 Precision Time Protocol (PTP) support has been part of Intel's controller product
line for generations. Intel only recently began developing PTP-optimized Ethernet Network Adapter
products. The adoption of PTP in Ethernet connections is growing rapidly. Although the leader use case
being considered is the build-out of 5G infrastructure, other applications that exist in datacenters, point
of presence, financial, industrial, and energy sectors. These application areas can benefit from timing
optimized, standard form factor, Ethernet adapters.
The Intel
®
Ethernet Network Adapter E810-CQDA2T (E810-CQDA2T), is based on the Intel
®
Ethernet
Controller E810 (E810).
