Emerging system requirements are driven by industry advancements in areas such as data centers, artificial intelligence, machine learning, and quantum computing, among others. Samtec 224 Gbps PAM4 interconnect systems are carefully designed to satisfy these high-performance requirements, as you’ll see in the video.
Ralph Page, Systems Architect at Samtec, gives an overview of what is possibly the world’s first public demonstration of an asynchronous 224 G system. This 224 G demo is from SC 23 (Super Computing 23, in Denver, Colorado).
It all starts with a Synopsys 224G Ethernet PHY IP, that’s transmitting 31-bit, PRBS data at 224 Gbps PAM4. The 224 data travels to a Samtec Bulls Eye® test point connector, then through low loss coax to Samtec 1.85 compression mount RF connectors on a Samtec evaluation board.
The signal goes to a Samtec Flyover® cable system, the high-density Si-Fly HD. From there, it travels through 14” of 34 AWG Eye Speed® ultra-low skew twinax cable, then the signal travels to end two of the Si-Fly HD connector system, then to a second Si-Fly™ HD evaluation board, through Samtec 1.85 mm compression mount RF connectors, to another Samtec Bulls Eye test point system on a second Synopsys 224 G PHY for analysis.
The performance of this LR channel is extremely impressive. The total loss exceeds 34 dBs at 56 GHz. The Pre-FEC BER is e-7. You can see from the plots just how impressive this is.
The Samtec Si Fly HD is the industry’s highest-density on-package or ASIC-adjacent cable system. By high-density, I mean it has 207 differential pairs per square inch. The cable is Samtec’s 34 AWG Eye Speed ultra-low skew twinax
