Keysight and KD Partner to Advance Multigigabit Optical Automotive Ethernet Testing With New Signal Analysis Capability
Keysight Technologies, Inc. (NYSE: KEYS) and KD, Inc., a fabless semiconductor company, have collaborated to create a comprehensive test for Multigigabit Optical Automotive Ethernet physical layer. The companies have jointly developed a Transmitter Distortion Figure of Merit (TDFOM) measurement and signal analysis metric validating PMD transmitter conformance based on the IEEE 802.3cz and Open Alliance.
Keysight Technologies, Inc. (紐交所: KEYS)與一家無廠半導體公司KD, Inc.合作,創建了多千兆光電汽車以太網物理層的綜合測試。這兩家公司聯合開發了一種發射器失真優點(TDFOM)測量和信號分析指標,以驗證PMD發射器的符合性,基於IEEE 802.3cz和Open Alliance。
Vehicles today contain over 100 million lines of code, pushing the limits of their hardware capabilities to support an unprecedented combination of infotainment systems, advanced driver-assistance systems (ADAS), and computing power. Future vehicle computing systems are evolving to be more centralized, with more software-defined features and greater data sharing between fewer engine control units (ECUs). Thus, backbone communications links push to ever-higher speeds in the multi-gigabits-per-second range.
如今的汽車包含超過10000萬行代碼,推動其硬件能力的極限,以支持前所未有的娛樂信息系統、高級駕駛輔助系統(ADAS)和計算能力。未來的汽車計算系統正在朝着更集中的方向發展,具有更多的軟體定義特性以及在更少的發動機控制單元(ECU)之間進行更多數據共享。因此,骨幹通信鏈路推動至更高的速度,達到每秒多千兆位的區間。
In response, the industry has created new automotive Ethernet standards, with IEEE 802.3cz being the highest data rate multi-gigabit standard. Published in 2023, this standard supports operations up to 50 Gb/s over glass optical fiber, specifying physical-layer requirements and management parameters for 2.5-, 5-, 10-, 25-, and 50-Gb/s operations in automotive environments. This standard is designed to meet the demands of modern in-vehicle networking platforms.
作爲回應,行業板塊創建了新的汽車以太網標準,其中IEEE 802.3cz是最高數據速率的多千兆位標準。該標準於2023年發佈,支持通過光纖玻璃進行高達50 Gb/s的操作,規定了汽車環境中2.5、5、10、25和50-Gb/s操作的物理層要求和管理參數。該標準旨在滿足現代車載網絡平台的需求。
The newly developed TDFOM measurement and signal analysis metric represents a significant advancement in evaluating multigigabit optical signal quality in glass optical fiber transmission. As specified in IEEE 802.3cz, TDFOM measurements utilize a reference receiver that models typical integrated circuit (IC) implementation, ensuring transmitter interoperability through signal integrity validation. This metric is essential for calibrating reference transmitters and enabling accurate compliance testing of optical receivers.
新開發的TDFOM測量和信號分析指標代表了在玻璃光纖傳輸中評估多千兆光信號質量的重大進展。如IEEE 802.3cz所規定,TDFOM測量利用模擬典型集成電路(IC)實現的參考接收器,確保通過信號完整性驗證發射器的互操作性。該指標對於校準參考發射器和進行光接收器的準確合規測試至關重要。
Combining KD's software-based reference receiver and signal metric analysis capabilities with Keysight's optical-to-electrical converter (O/E) and oscilloscope technology delivers a comprehensive testing platform that evaluates a transmitted optical signal's ability to achieve the required system Bit Error Rate (BER) after passing through a worst-case optical channel and a reference receiver. This collaborative development emerged from both companies' active participation in establishing the final TDFOM specification during the IEEE 802.3cz standard development.
將KD的基於軟體的參考接收器和信號指標分析能力與Keysight的光電轉換器(O/E)和示波器技術相結合,提供了一個全面的測試平台,評估傳輸的光信號在經過最壞情況下的光通道和參考接收器後,達到所需系統比特錯誤率(BER)的能力。這一合作開發源於兩家公司在IEEE 802.3cz標準開發過程中積極參與建立最終TDFOM規範。
Rubén Pérez-Aranda, KD's CTO and co-founder, said: "With this agreement, we make a big step in providing OEMs and Tier-1 companies with the necessary means to test the quality of developments incorporating optical communications according to the IEEE Std 802.3cz. Keysight and KD have collaborated in IEEE 802.3 to define the tests and metrics that ensure the new Ethernet communications standard meets the quality requirements demanded by the automotive industry."
Rubén Pérez-Aranda,KD的首席技術官兼聯合創始人表示:「通過這項協議,我們在爲OEM和一級供應商提供必要手段,以根據IEEE Std 802.3cz測試光通信開發的質量方面邁出了重要一步。Keysight和KD在IEEE 802.3中合作定義了測試和指標,以確保新的以太網通信標準滿足汽車行業所要求的質量標準。」
Thomas Goetzel, Vice President and General Manager of Keysight's Automotive & Energy Solution, highlighted the importance of this agreement: "Automotive Ethernet technologies have evolved and now derive significant benefits from optical fiber technologies for enabling multigigabit in-vehicle networking. Our innovative test and measurement equipment, combined with KD's expertise in optical measurements, aims to assist customers in exploring reliable high-speed links in in-vehicle networking."
Keysight汽車與能源解決方案的副總裁兼總經理Thomas Goetzel強調了這項協議的重要性:「汽車以太網技術已經發展,現在從光纖技術中獲得了顯著的好處,以支持多千兆位的車載網絡。我們的創新測試和測量設備,以及KD在光測量方面的專業知識,旨在幫助客戶探索車載網絡中的可靠高速度鏈接。」
This partnership combines KD's expertise in new technology development with Keysight's test equipment to assist OEMs and Tier-1 companies validate and optimize next-generation technologies. It drives innovation, enhances interoperability, and encourages the adoption of advanced optical communication standards across the automotive sector.
這一夥伴關係結合了KD在新技術開發方面的專業知識與Keysight的測試設備,以幫助OEM和一級供應商驗證並優化下一代技術。這推動了創新,增強了互操作性,並鼓勵推動先進光通信標準在汽車行業的應用。
