NVIDIA offers a full IEEE 1588v2 PTP software solution, as well as time-sensitive related features
called "5T". NVIDIA PTP and 5T software solutions are designed to meet the most demanding
PTP profiles. ConnectX-6 Dx incorporates an integrated Hardware Clock (PHC) that allows
ConnectX-6 Dx to achieve sub 20u Sec accuracy and also offers many timing-related functions
such as time-triggered scheduling or time-based SND accelerations (time-based ASAP²).
Furthermore, 5T technology enables the software application to transmit fronthaul (ORAN)
compatible in high bandwidth. The PTP part supports the subordinate clock, master clock, and
boundary clock.
ConnectX-6 Dx PTP solution allows you to run any PTP stack on your host.
With respect to testing and measurements, selected NVIDIA adapters allow you to use the PPS-
out signal from the onboard SMA connecter, ConnectX-6 Dx also allows measuring PTP in scale,
with PPS-In signal. The PTP HW clock on the Network adapter will be sampled on each PPS-In
signal, and the timestamp will be sent to the SW.
Enabled in MCX623106PN-CDAT, MCX623106PC-CDAT, MCX623106TN-CDAT, MCX623106TC-CDAT,
MCX623106GN-CDAT, and MCX623106GC-CDAT.
