Demonstrations with Amphenol (Booth #635), Amphenol FCI (Booth #533) and Molex (Booth #817) leverage Credo's 56G NRZ SerDes IP evaluation platform and Credo's recently announced 100G CMX12520 multiplexer (MUX)/retimer chip -- enabled by Credo's 56G PAM-4 SerDes -- to drive error-free connectivity over copper cables, orthogonal backplanes, and cable backplanes. The 56G NRZ demonstrations highlight the fact that high performance computing (HPC) environments have the ability to deploy low latency, error-free systems without the need for forward-error correction (FEC). Additionally, Credo is demonstrating long-reach 28G technology with Lorom (Booth #502), showcasing highly malleable 3-meter and 5-meter copper cables for data center connectivity.

Demonstrations with Amphenol FCI

Credo will conduct two demonstrations with Amphenol FCI. The first will show 56G NRZ transport over FCI's ExaMAX® direct-mate orthogonal interconnect system. The second demonstration will show 56G PAM-4 transport over the same architecture.

"Now that FCI is a member of the Amphenol family, we can collaborate with our sister divisions to offer an unmatched portfolio of high-speed interconnect solutions," said Dana Bergey, signal integrity manager at Amphenol FCI. "ExaMAX® connectors have become a very popular choice for 28G applications around the globe, including standard backplane, midplane, mezzanine, coplanar, and direct-mate orthogonal versions. We are excited to work with Credo to show how ExaMAX products can successfully pass 56GB signals -- error-free -- with all the popular encoding techniques."

Demonstration with Lorom

Credo will conduct two demonstrations with Lorom. In addition to driving error-free 28G signals across standard Lorom Emaxx cables at lengths up to eight meters, the Credo 28G SerDes IP evaluation platform will be leveraged to demonstrate error-free transmission across Lorom's light-weight and highly flexible three-meter and five-meter cables in both SFP and QSFP form factors. 

Lorom's bulk cable performance utilizes low-loss foamed dielectric, low surface roughness foils and proprietary manufacturing processes to achieve among the lowest insertion loss per meter in the industry. In addition to having this low insertion loss performance, Lorom's well-balanced cables exhibit nominal mode conversion below 30dB. This further minimizes insertion loss and provides consistent pair-to-pair performance.

"The combination of Lorom's advanced cabling technology and Credo's industry leading SerDes technology enables signals to be pushed farther in length, across cables with smaller outer diameters, without the need for FEC," said Henning Hansen, chief operating officer of The Lorom Group. "The small size, light weight and extreme malleability of these cables should have a profound impact on front-panel data center rack connectivity."

Demonstrations with Molex

Credo will conduct two demonstrations with Molex. For the first demonstration, Credo will supply transmitting and receiving electronics, showing error-free 56G NRZ and 56G PAM-4 live serial traffic on the zQSFP+™ form factor using a high-speed copper cable. The second demonstration will highlight the Molex Impel™ backplane cable assembly driving 56G speeds in both NRZ and PAM-4 applications.

"This demonstration will highlight the feasibility of running extremely high, next-generation data rates, even on form factors that are already in use," said Joe Dambach, product manager, Molex. "By pairing our advanced cabling solutions with Credo SerDes technology, we can show groundbreaking signal integrity performance at very high speeds."
