PPS In/Out

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

SMAs

features called "5T". Mellanox PTP and 5T software solution 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, the 5T technology enables the software application to transmit fronthaul

(ORAN) compatible in high bandwidth. The PTP part supports slave 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 Mellanox adapters allow you to use the PPS-

out signal from onboard SMA connecter, ConnectX-6 Dx also allows to measure 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, MCX623106PE-CDAT and MCX623106PC-CDAT.
