San Jose, Calif. \u2013 April 6, 2022<\/span><\/b>\u00a0<\/span><\/p>

Hirose Electric Co., Ltd., a global leader in connector technology, its design, and manufacturing, and eTopus Technology, a pioneer of ultra-high-speed ADC\/DSP-based SerDes for wireline applications including data center, cloud, edge, and 5G base stations, today announced the development of a 64Gbps PCIe Gen6 interconnect technology built on their products. This combined solution is ideally suited for linking graphics processing units (GPUs) into a fully connected mesh for artificial intelligence (AI) and machine learning (ML) applications. The interconnects use 64Gbps four-level pulse amplitude modulation (PAM4) technology to pack the maximum possible bandwidth into each communication channel.<\/span>\u00a0<\/span><\/p>

The bench setup demonstrating this solution features the eTopus 64Gbps PAM4 PCIe Gen6 ePHY<\/span>\u2122 <\/span>SerDes IP evaluation board (EVB) with transmit (TX) and receive (RX) pairs connecting to Hirose\u2019s IT9 or IT12 connector paddle cards via Huber+Suhner connectors and cables, mimicking the full data path of a networking system. Four channels are connected with the worst-case crosstalk configuration using three near end crosstalk (NEXT) aggressors most adjacent to the victim pins in the connector. Pseudo-random bit stream (PRBS) data traffic is generated at the TX and FIR (finite impulse response) conditioned signals are then sent through Hirose\u2019s interconnect system (with additional insertion loss from the eTopus breakout board). At the EVB RX, analog to digital converters (ADCs) digitize the incoming bit stream, fully adaptive digital signal processing (DSP) equalizes the signal levels, and finally the clock and data recovery (CDR) realizes the data stream. PRBS errors are registered in the error counter and error statistics is used for pre-FEC (forward error correction) and post-FEC bit error rate (BER) analysis.\u00a0<\/span>\u00a0<\/span><\/p>

Hirose is a major supplier to Tier-1 network, system, and cloud providers. Its products include connectors and connectivity solutions for a wide range of applications. The project with eTopus uses formally-released next-generation connector (IT9 or IT12) to leverage state-of-the-art technology. To meet a wide range of different system design requirements, Hirose\u2019s IT9 and IT12 interface connectors offer both a R\/A or cardedge interface, which allows module\/daughter card system design to optimize its mechanical and airflow\/thermal designs.\u00a0\u00a0<\/span>\u00a0<\/span><\/p>

eTopus is a provider of serializer\/deserializer (SerDes) IP for high-speed communications applications. The eTopus high-speed transceiver architecture substantially enhances system BER performance and CDR robustness while reducing system cost and power consumption for networking, storage, and 5G applications. Their industry-leading technology provides excellent BER for long reach applications, excellent post-FEC with minimal decision feedback equalizer (DFE) error propagation for medium to long reach with crosstalk, and low-latency FEC, suitable for AI types of interconnects.<\/span>\u00a0<\/span><\/p>

Combining eTopus\u2019 64Gbps PCIe Gen6 ePHY advanced SerDes architecture with Hirose\u2019s interconnects, the channel impairments induced correlated errors are minimized without observable bursty symbol errors. This characteristic is critical for the forward error correction (FEC) decoder to correctly recover any erroneous codeword and to reduce the frame loss rate even with FLIT\u00a0 cheme of PCIe Gen6 to maintain data integrity at 64Gbps operation.<\/span>\u00a0<\/span><\/p>

\u201cWe were pleased to collaborate with eTopus on this project,\u201d said Mr. Tsutomu Matsuo, General Manager of Hirose\u2019s High-Speed Interconnect Division. \u201cWe were able to demonstrate that our latest connector technology can reliably communicate using advanced SerDes technology. This combination will be valuable to many of our customers.\u201d<\/span>\u00a0<\/span><\/p>

\u201cWhen developing high-speed IP solutions, it is important to test them in a real-world environment,\u201d said Harry Chan, founder & CEO of eTopus. \u201cThe Hirose connector allowed us to build a bench setup using our IP in a fully connected mesh. We appreciate their support on this project.\u201d<\/span>\u00a0<\/span><\/p>

The bench configuration built using the combined interconnect solution will be demonstrated at <\/span>DesignCon<\/span><\/a> in Santa Clara Convention Center on April 5-7<\/span>th<\/span>.\u00a0 The demonstration showcases its revolutionary ePHY SerDes IP.<\/span>\u00a0<\/span><\/p>
