Feature

Time

Sensitive

NVIDIA offers a full IEEE 1588v2 PTP software solution, as well as time-sensitive related

Applications

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.

Enhanced-

SyncE &

NVIDIA offers ConnectX-6 Dx cards with SyncE support including an improved holdover to meet

PTP

ITU-T G.8273.2 class C.

Enabled in MCX623106TN-CDAT, MCX623106TC-CDAT,

CDAT.

Grand

Master

NVIDIA offers ConnectX-6 Dx with an integrated GNSS receiver to allow a compact and efficient

(GNSS

solution for a Grand Master at every server.

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.
