What do the QSFP-DD800 MSA and VITA 57 have in common? Fair question. One focuses on defining the next-gen pluggable form factors while the other complements FPGA mezzanine applications.
So what is the link? Samtec, of course! Samtec participates in many Industry Standards to develop commonality is specific applications. QSFP-DD800 and VITA 57 are but two examples.
QSFP-DD800 MSA: New HW Spec
For the record, QSFP-DD800 refers to “Quad Small Form Factor Pluggable Double Density 800”. The goal of the MSA is to scale development of high-speed, double-density QSFP modules which support 800 Gbps connectivity.
Why all the fuss about QSFP-DD800? Well, QSFP solutions are commonplace connector, cage and transceiver form factors across the majority of data center applications. Current QSFP-DD solutions can handle 400 Gbps (8 x 50 Gbps), but QSFP-DD800 moves it to 800 Gbps (8 x 100 Gbps).
The new QSFP-DD800 efforts have focused on SI improvements for increased performance per lane. For example, optimized transceiver pads allow for 100 Gbps performance. Additionally, a new 2×1 connector/cage definition allows upper ports to leverage high-performance twinax cables options instead of traditional PCB traces.
Novel interconnect architectures also assist in thermal management similar to Samtec FQSFP-DD solutions shown above. Yet, the the QSFP-DD800 MSA has focused on being backward compatible with previous QSFP modules.

New VITA 57.X Application Notes
VITA 57.X? That’s never been covered on the Samtec blog, right? Thanks for enduring that bit of sarcasm! 🙂
By any measure, both VITA 57.1 FMC and VITA 57.4 FMC+ have been extremely popular standard interfaces. FPGA vendors like Xilinx, Intel, Achronix and others and their ecosystem partners leverage FMC and FMC+ across their hardware platforms.
Samtec, of course, is the connector provider for both VITA 57.1 FMC and VITA 57.4 FMC+. Additionally, Samtec has developed a number of accessories that complement the VITA 57.X connector solutions.
As customers increase the amount of FMC and FMC+ information requests, Samtec has created several application notes that assist with design and testing VITA 57.X interfaces:
- VITA 57.4 FMC+ Extender Application Note
- VITA 57.4 FMC+ Loopback Cards Application Note
- Mechanical Design of Micro Jack Screw Precision Board Stacking Standoff Application Note
- Mechanical Design of High Data Rate Cable Assembly for VITA 57.4 Application Note
