A key component of any high-speed signal path is the interconnect. Design engineers must identify the right connector (or connectors) and the best performance for the application. At 56 Gbps PAM4 data rates (and higher), connector selection becomes more challenging. Interconnect manufacturers like Samtec make connector performance data readily available to support the connector selection process. Measured data in the form of S-parameters are often the most trusted, but just how good are … [Read more...]
Connector Designs To Address Data Rate and Density Challenges
Demand For High Data Rate As the need for bandwidth continues to increase, so does the need for higher data rates within a system. What was once one to three Gbps, then moved to 4 to 8 Gbps, and now we are approaching 28 Gbps and looking forward to 56 G. This trend was recently driven home at DesignCon 2018, where many exhibitors were demonstrating interconnects running at 112 Gbps PAM 4. Although the Datacom and Telecom industries are abuzz pushing these cutting-edge data rates, achieving … [Read more...]
Samtec Demonstrates 56 Gbps PAM4 QSFP-DD Cable Solution
56 Gbps, PAM4 System A new breed of cable solution is benefitting designers by reducing board size and improving signal performance -- either across the board, between boards, or from board-to-front panel. In this video, Ralph Page walks us through a combined Xilinx and Samtec 56 Gbps PAM4 FQSFP-DD to AcceleRate® cable demonstration. The QSFP-DD pluggable form factor, which supports 400 Gbps throughput – that is, 8 X 50 Gbps – is going to define front panel I/O on next generation … [Read more...]
Samtec Demonstrates Next Gen SiPho COBO Platform
COBO, Silicon Photonics Kevin Burt, Application Engineer at the Samtec Optical Group, walks us through a demonstration using silicon photonics and the COBO (Consortium of Onboard Optics) form factor. This was displayed at OFC 2018 in San Diego, California. Samtec is a fabless integrator for optics. This means we have the choice of the right technology for engineers and designers, and their applications. We can accomplish this with several different protocols, including Ethernet, … [Read more...]
