Product Description
The NVIDIA Mellanox ConnectX-6 Dx EN MCX623106GC-CDAT is the most timing-capable member of this ConnectX-6 Dx EN batch, combining Secure Boot, hardware Crypto offload and Enhanced-SyncE & PTP with Grandmaster (GM) support and GNSS-sourced PPS output. It connects via a PCIe 4.0 x16 host interface and provides two 100GbE QSFP56 ports with RoCE v2 RDMA offload for low-latency, high-throughput networking. Its integrated GNSS receiver and PTP Grandmaster capability let the adapter act as an authoritative, satellite-disciplined time source for the network — distributing precise time to downstream devices without depending on an external grandmaster clock. Secure Boot protects firmware integrity, while the Crypto engine offloads inline data-in-motion encryption from the host CPU. This combination makes the MCX623106GC-CDAT particularly well suited to telecom, financial trading, industrial automation and any deployment where the server itself must serve as a trusted, precise time reference for the surrounding network infrastructure.
