(For full disclosure, this blog has been written by a real person. Or has it? 😉) In any case, the backbone of chatbots like ChatGPT and similar services are high-performance compute platforms enabling neural networks and AI acceleration in data centers. Obviously, GPUs have a leadership position in AI hardware … [Read more...]
High-Speed Cable System and Blockchain ISI Demonstrate Excellent 112 Gbps PAM4 Performance
OFC 2023 saw the world premiere of Credo’s DOVE 800 family, teamed with a Samtec Flyover cable assembly, and a Samtec blockchain ISI board, both demonstrating outstanding performance at 112 Gbps PAM4. The DOVE 800 is a retimer, with eight lanes of 100 G to 100 G. Ralph Page, Systems Architect at Samtec, walks us through the two signal paths. In channel one, a BERT is generating eight lanes of 112 Gbps PAM4, PRBS 31-bit data, which travels through low-loss coax cable to a Samtec … [Read more...]

New 112 Gbps PAM4 NovaRay™ SI Eval Kit Featured at Keysight Event
"112 Gbps PAM4 data rates will save the world!" A reader of the Samtec blog may think that. Why? The demand for data never ceases. A recent report says that US teenagers spend seven hours a day in front of screens. But how real are 112 Gbps PAM4 data rates? Test silicon is available from a few SerDes and FPGA vendors. Production silicon is at least 18 months away. However, 112 Gbps PAM4 data rate system design and testing are already underway. The SI requirements for next-gen … [Read more...]
