Feature Description
Time
Sensitive
Applications
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.
Enhanced-
SyncE &
PTP
NVIDIA offers ConnectX-6 Dx cards with SyncE support including an improved holdover to meet
ITU-T G.8273.2 class C.
Enabled in MCX623106TN-CDAT, MCX623106TC-CDAT, MCX623106GN-CDAT, and MCX623106GC-
CDAT.
Grand
Master
(GNSS
Reciver)
NVIDIA offers ConnectX-6 Dx with an integrated GNSS receiver to allow a compact and efficient
solution for a Grand Master at every server.
Enabled in MCX623106G[N/C]-CDAT

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.
