The 802.3cz standard draft for the automotive industry specifies speeds starting at 2.5 Gb/s and going up to 50 Gb/s. The 802.3 Task Force includes numerous individuals affiliated with key carmakers, such as PSA, Toyota, BMW, Ford, GM, and Volvo; Tier 1 suppliers; and components suppliers. These industry leaders have been working on an optical automotive multi-gigabit system that will fulfill the needs of future connected and automated vehicles. “We are very thankful and positive about the strong support from the industry,” added Pardo.

KDPOF proudly announced that their well-proven KD1053 PHY IC and integrated KD9351 FOT (Fiber Optic Transceiver) have been implemented by Renesas, a premier supplier of advanced semiconductor solutions, into the new next generation automotive vehicle computer VC4. This comprehensive communication gateway ECU from Renesas features the newest automotive network technologies and sufficient computing power to host the ever-increasing number of user applications. “With the VC4, we have integrated an optical Ethernet interface into our automotive evaluation boards for the first time,” stated Tobias Belitz, Principal Engineer at Renesas. “KDPOF shared their 1000BASE-RH transceiver KD1053 and KD9351 FOT according to IEEE 802.3bv with us, which also covers the wide temperature range we are looking at.”

The four megatrends of autonomous driving, connected cars, electric vehicles, and shared mobility move the E/E architecture from domain based into a zonal architecture in order to meet the increasing complexity and computation demands of the next generation vehicles. With the VC4 communication gateway ECU, Renesas provides a universal development platform for automotive customers based on their R-Car-S4 system-on-module.

KDPOF Chipset for Safe Backbone and ADAS Sensor Connection

Optical connectivity perfectly solves the challenges posed by electrical interference in vehicles thanks to its low weight, low cost, and electromagnetic compatibility due to inherent galvanic isolation. “We are proud that Renesas has chosen our compact automotive Ethernet chipset for their future-ready vehicle computer VC4,” stated Carlos Pardo, CEO and Co-founder of KDPOF. “With the integrated KD9351 FOT in combination with the KD1053 PHY IC, we deliver a complete automotive 1000BASE-RHC physical layer.“ Applications include safe Ethernet backbones, smart antenna modules, and sensor connections for ADAS and audio/video.

Incorporating the transmission and reception optoelectronics – such as transimpedance amplifier, photodiode, LED driver, and LED – into one single component, the KD9351 is an optical transceiver for 100 Mb/s up to 1 Gb/s with a small footprint. Additional benefits are a shorter supply chain and no test duplication with the final test at the Tier1. Furthermore, the assembly is simplified and the connector offers snap-fit without soldering. The KD9351 reuses low-cost MEMs encapsulation and allows SMD reflow assembly with 8 by 7 mm LGA components. It is fully shielded against electromagnetic radiation. The temperature range, from -40 °C to +105 °C, conforms with harsh automotive environmental requirements.

KDPOF is looking forward to participating in the upcoming virtual ISCAS 2020 from October 10 to 21 with several contributions: a presentation on multi-gigabit Ethernet for the automotive industry, an overview lecture on high-speed data communications over POF, and an important role in the final industry panel session. The IEEE International Symposium on Circuits and Systems (ISCAS) is the flagship conference of the IEEE Circuits and Systems (CAS) Society and the world’s premiere networking forum for researchers in the highly active fields of theory, design, and implementation of circuits and systems.

Presentation: Towards the Multi-Gigabit Ethernet for the Automotive Industry

On Tuesday, October 13, 2020, from 17:15 to 18:55, session Chairmen Enrique Prefasi Sen, Analog and Mixed Signal Senior Designer of KDPOF, and Alberto Rodríguez-Pérez, Analog and Mixed Signal Manager of KDPOF, will present the paper “Towards the Multi-Gigabit Ethernet for the Automotive Industry”. The paper, within the special session “Multi-gigabit Wireline & Optical Communication Circuits & Systems Session”, will show the status of Ethernet-based communication solutions, focused on optical links for the automotive industry. First, the presenters will display the implementation of a product compatible with the 1000BASE-RHC according to the IEEE Std 802.3bv, which is the first one able to transmit 1 Gbps over POF for automotive. Second, the KDPOF experts will describe a new architecture to achieve up to 25 Gbps for automotive. The proposed multi-gigabit system leverages existing technologies such as VCSELs, multi-mode fibers, and photodiodes already developed for the data center industry.

Lecture: High-Speed Data Communications over Plastic Optical Fibers

Alberto Rodríguez-Pérez will give an overview lecture on Saturday, October 17, 2020, from 16:00 to 16:45 in virtual room 2. In his lecture, Alberto will show an overview of the use of Plastic Optical Fiber as a medium for optical data communications and the techniques needed to get high speed data bitrates over POF. It is an interesting alternative optical communication channel to the Glass Optical Fibers (GOF) for applications that are not required to cover long distances, such as home or automotive networking. However, the reduced low bandwidth of the POF channel imposes big limitations in the maximum data bitrate that can be transmitted through this medium. Consequently, advanced data communication techniques such as channel equalization, data error correction, or data signal modulation need to be applied to achieve data bitrates above 1 Gbps.

Industry Panel

KDPOF is also substantially involved in the final Industrial Panel Discussion on Wednesday, October 21, 2020, from 16:45 to 17:45. Alberto Rodríguez-Pérez will chair the panel and Rubén Pérez de Aranda, CTO of KDPOF, will participate as panelist.

Aukua Systems Inc., provider of Ethernet test and monitoring solutions, and KDPOF are proud to announce the success of their technology partnership for ISO 21111 standardization. Recently, two additional sections, ISO 21111-3:2020 and ISO 21111-5:2020, of the international in-vehicle Ethernet ISO standard series 21111 have been published. “By providing their MGA2510 Ethernet Test and Monitoring Platform, Aukua Systems have supremely equipped the test setup for ISO certification,” stated Carlos Pardo, CEO and Co-founder of KDPOF.

KDPOF supports the test ecosystem to make sure that ECUs including their technology will be tested by recognized test houses and based on the ISO standard. “We are delighted to support the overall standard for optical gigabit connectivity in vehicles with ISO 21111 complementing the existing IEEE Std 802.3bvTM,” added Suds Rajagopal, Co-Founder at Aukua Systems. “By leveraging Aukua’s test solutions, carmakers and Tier1s now have access to a complete, compatible, and interoperating implementation based on these standards.”

ISO 21111 Standardization

For reliable implementations of systems that implement in-vehicle Ethernet Optical 1 Gb/s as a physical layer, International Organization for Standardization (ISO) has added two new sections to the in-vehicle Ethernet series 21111: ISO 21111-3:2020 specifies additional features to IEEE 802.3bv, such as wake-up and synchronized link sleep algorithms. ISO 21111-5:2020 specifies requirements at the system level and a complete conformance and interoperability test plan for ECU providers that implement optical 1 Gb/s physical layer as specified in ISO 21111-3.
