Collaboration validates 12G interconnect for high-speed IP
www.edn.com, Sept. 21, 2021 –
eTopus taps Amphenol ICC's ExaMAX2 112-Gbps interconnect for its ADC/DSP-based serializer/deserializer (SerDes) IP. The combined products can be used for high-speed communications, machine learning, artificial intelligence, and industrial and instrumentation applications.
The two companies conducted a demonstration using the eTopus 112-Gbps ePHY SerDes IP evaluation board with four transmit and receive pairs and connecting two of Amphenol's 4-pair backplane right-angle receptacles with a 1-meter ExaMAX2 I/O assembly. The bench setup achieved ultra-low latency of under 25 ns and post-ULL FEC BER of 3e-17.
"We are excited to work with an industry interconnect leader like Amphenol and validate their ExaMAX2 connector and 1 meter copper cable with our 112-Gbps SerDes IP. This end-to-end demonstration provides a clear upgrade path for modular platforms to double the line card bandwidth from 12.8 Tbps to 25.6 Tbps with electrical signaling and their chassis dimension," said Harry Chan, CEO of eTopus. "We are exceptionally pleased with the low bit error rates with no channel impairment concern when utilizing the new Amphenol connector with our latest 112G ePHY SerDes."
The ExaMAX2 backplane connector system meets OIF 112-Gpbs PAM4 and IEEE 100-Gbps PAM4 industry specifications. A beam-on-beam mating interface provides low crosstalk, while eliminating insertion loss resonances. It also reduces mating force by up to 65% compared to conventional blade and beam designs. ExaMAX2 is available in both 90-Ω and 85-Ω versions.
