Automotive Ethernet Congress: Automotive Multi-gigabit is Optical

With new challenges like automated driving and electric power trains, In-Vehicle Network (IVN) requirements are quickly evolving. The IVN has to support use cases such as the vehicle data backbone, smart antennas, ADAS cameras/sensors, displays, and data loggers, which demand higher data bandwidth while maintaining the reliability level required by the automotive industry. When considering a standard technology to support the target use cases, it is clear that the requirements are not all met by any existing communication standard, including the optical 10GBASE-SR. It is thus necessary to define a new IVN standard for multi-gigabit optical communications in the automotive environment.

On June 2, 2022 at 10:00 CEST, Carlos Pardo will give the presentation “Automotive Optical Ethernet Reaching for 50 Gb/s” at the Automotive Ethernet Congress in Munich, Germany. At stand 26 in the exhibition area, we will present latest highlights of our optical in-vehicle network technology from June 1 to 2. Carlos and our team look forward to meeting you in Munich. Please contact us to set up a date. We are happy to pass on a 10 percent discount to our customers and business fellows.

Automotive Optical Ethernet Reaching for 50 Gb/s

A new optical automotive IVN communication standard is currently under development within IEEE under the name 802.3cz. It is supported by several industry-leading companies. The new standard will cover rates up to 50 Gb/s, will support several in-line connectors and will have BER better than 10-12 with ECU ambient operation temperature from -40ºC up to 105ºC in harsh automotive environments. High reliability and outstanding EMC compliance will also be fulfilled.

In parallel with the standardization effort, KDPOF is developing an optical transceiver capable of supporting the new standard requirements. It will enjoy low power dissipation and automotive industry-standard cost. KDPOF´s new optical port is based on a small and scalable connector with a minimal PCB area impact. The new KDPOF technology will enable symmetric links, as well as strongly unbalanced upstream/downstream rates suitable for applications such as sensors, cameras and displays.

As the auto industry approaches the 100 Gb/s*m speed-length threshold, the need to move away from copper and toward optical physical data transmission media is becoming mandatory. Copper transmission may try to cope with the new requirement by adding parallel lanes, thicker cables and shielding, impacting the cost and weight of cables as well as their mechanical flexibility and port size. Moreover, copper ports will require a higher DSP complexity, which quickly translates to high power consumption and bigger latencies. Last but not least, copper will operate at higher signal amplitude to comply with the required error rate, which will result in a worse EMC behavior and will also penalize power consumption.

Optical is the engineering-wise path for higher data rates. It will support Energy-Efficient Ethernet and wake-up & sleep. The technology in development by KDPOF is based on advanced digital signal processing and on high-speed ADC to implement all the needed algorithms. Key elements of the communication system, where several industry leaders are also working, are the VCSEL, multimode fibers, cable structure and connectors.

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.”

1000BASE-RHC Optical Physical Layer Adds Robust and EMC-safe Network Interface to Communication Gateway ECU

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.
