Knocking On The Door To 112 G PAM4
Channel rates have evolved from 28 Gbps NRZ to the current 56 Gbps PAM4, with 112 Gbps PAM4 in-development and knocking at the door. This live product demonstration shows the door is opening with a cutting-edge 112 G test chip and two new high-performance connector systems. It’s all driven by the Alphawave AlphaCORE 100 Long-Reach Multi-Standard SERDES. This is a high-performance, low-power, DSP-based PHY. The new connector products are the Samtec NovaRay® extreme density array … [Read more...]
New High Speed Connector System: 56 Gbps PAM4 SI Evaluation Demonstration
Here's a live product demonstration of a new high speed connector system which achieves excellent SI results while running at 56 Gbps PAM4. Jean-Remy Bonnefoy, Systems Engineer at Samtec, explains how Samtec partnered with Credo for this active product demonstration. Credo’s mixed signal 56 Gbps PAM4 Bald Eagle 2 silicon generates two bi-directional channels of QPRBS-31 signal data at 56 Gbps PAM4. The differential signals travel through 2" of traces on a MEG4 PCB, to a Samtec … [Read more...]
Demand For High Bandwidth Systems Keeps Growing – 112 Gbps and More
The pandemic has not slowed the demand for high bandwidth, high-performance systems, such as 56 Gbps PAM4, 112 Gbps PAM4 and more. Designer engineers in all types of industries, from data center, HPC, networking, telecom, medical, storage, semiconductor, wireless, test and measurement, automation and security, to name a few, continue to develop architectures to accommodate the seemingly insatiable demand for data. Earlier this year, when we were participating in live conferences and … [Read more...]
Convergence: A Key to 224 Gbps PAM4 System Design
Convergence in technology is not a new idea; it infers that disparate technologies evolve to a closer association or integration over time. Many believe convergence is required for future 224 Gbps PAM4 system performance. Samtec’s Scott McMorrow and Matt Burns recently authored the article “Convergence: Key to 224 Gbps PAM4 System Design” for Signal Integrity Journal. It’s worthwhile to read the entire article, but if time doesn’t permit, the rest of this blog is a summary of the key … [Read more...]
56 Gbps PAM4 Connector Product Demonstration
In the video above Ralph Page, Systems Architect at Samtec, walks us through a live product demonstration that received a lot of attention at Super Computing 2019. Ralph discusses several Samtec 56 Gbps PAM4 connector solutions and shares some incredible results. The system can also run up to 28 Gbps NRZ. This is a fully-packaged system that populates signal paths using real-world signal integrity design practices. It demonstrates up to 56 Gbps PAM4 signaling, utilizing Samtec Flyover® … [Read more...]
A 112 Gbps High-Density Escape From The System ASIC To The Front Panel
In this video from EDI CON 2109, Samtec's Jignesh Shah explains how Samtec Flyover® offers a 112 Gbps high-density escape from the system ASIC to the front panel. This is a live demonstration of 112 Gbps PAM4 traffic using Credo Semiconductors mixed signal SERDES with Samtec Flyover technology. First, Jignesh walks us through the signal path: A Credo Firebird SERDES generates 31-bit PRBS data at 112 Gbps PAM4 data rates.The signals travel from the Credo test board, through precision … [Read more...]
A Connector Solution To Achieve 112 Gbps Data Rates
In the video above, Samtec's Jignesh Shah and Kevin Burt explain that as data rate requirements approach and surpass 112 Gbps PAM4, developers are challenged with balancing increasing throughput, scalability, and density demands with concerns such as power consumption, signal integrity, time-to-market, and of course cost. To hit these speeds, designers often have to use special board laminate materials with lower dielectric constants and dissipation factors. But the problem is, these … [Read more...]
5 Meter, 56 Gbps Long Reach Backplane Cable Assembly For Rack to Rack Applications
Long Reach Backplane Cable This live demonstration from DesignCon 2019 shows how Samtec's ExaMAX® backplane connector, combined with Samtec Flyover® technology, achieves high density and very long reach. Here, the reach is five meters for a rack-to-rack interconnect system. In this video, Samtec's Gustavo Blando walks us through the topology and discusses system performance. Samtec Flyover systems can be used in mid-board applications to achieve next gen speeds with longer reach … [Read more...]
112 Gbps Interconnect Increases Reach Between the ASIC and the Front Panel
In this demonstration at DesignCon 2019, J.R. Bonnefoy (a Systems Engineer at Samtec) explains how Samtec Flyover® offers a 112 Gbps high-density escape from the system ASIC to the front panel. Signal Path A Credo Pelican II SERDES generates 31-bit PRBS data at 112 Gbps PAM4 data rates. Signals travel from the Credo test board, through precision RF cable assemblies, to a Samtec NovaRay cable assembly SI evaluation board. The signals then route through the NovaRay board, to the … [Read more...]
