DRIVING TOWARD AN EMISSIONLESS FUTURE IN TRANSPORTATION THE CAR IN THE AGE OF CONNECTIVITY THE MATEnet INTERCONNECTION SYSTEM TE's MATEnet interconnection is a proactive answer to today's and tomorrow's requirements for vehicle connectivity. MATEnet modular and scalable connectors are specifically developed for IEEE Automotive Ethernet networking. Its miniaturized, robust, automotive—grade technology; has successfully passed severe testing and validation. TE's MATEnet relies on NanoMQS terminals, which are automotive-grade contacts miniaturized, contacts that offer a particularly high robustness against vibration. Standard unsealed NanoMQS connectors meet severity level 2 vibration requirements (around 3g effective random and 30g shock). Sealed connector versions can also meet vibration level 3 ("close to powertrain") and 4 ("engine mounting"). MATEnet Cable Assembly (UTP/STP): Available cable types: UTP 100 Mbps / UTP 1 Gbps and STP 1 Gbps Possible Configurations: 1 port Frame – 1 port Frame 1 port Frame – 1 port Inline Coupler Female insert – Female insert Female insert – Male insert However, high-frequency, high-bandwidth data transfer poses strict requirements to signal integrity. The effort and cost required to fulfill individual Automotive Ethernet application needs is typically a product of measures that are integrated in the chip and the effort that goes into the channel (cable and connectors). TE's MATEnet was designed to offer an optimum balance between both cost curves. It delivers an excellent cost- performance ratio because it neither places a high burden on chip capabilities (size, power consumption) nor does it require high-end cabling (materials, processes, complexity). m at e - a x r f i n t e r c o n n e c t o r s ADAS units may have as many as 24 coax inputs coming from the many sensors required for detecting objects and free space around a vehicle. Coaxial cables provide an economic and easy to handle physical layer for RF-signal transmission. But coax, automotive-grade interconnection solutions such as FAKRA may not provide enough RF-performance for ADAS. The challenge for TE was to quadruple the number of coax cables that can be terminated as compared to a FAKRA connector, and to double the amount of lines in comparison to a High Speed Data (HSD) differential signaling connector. MATE-AX is the result. MATE-AX provide an EMI resistant and miniaturized interconnection RF-solution for existing and future coax lines. With excellent signal integrity and the long-term potential for up to 20 GHz, MATE-AX take automotive coaxial technology to the next level of performance and facilitate transmission of large uncompressed data between signal sources and ECU "servers." By offering a higher packaging density (4 coax cables in the space of 1 FAKRA connectors; 2 coax cables in the space of 1 HSD connection), MATE-AX terminals support significant size and weight reductions, and give the industry a solid, future-proof digital signaling roadmap. m at e n e t i n t h e f u t u r e — P o w e r - ove r - D a t a - L i n e ( P o D L ) — Currently, electronic devices in cars are supplied with electricity over separate cables. However, the additional cables make the harness heavier, more complex, and more difficult to feed parts of the harness through narrow passageways within vehicles. It would therefore be a contribution to downsizing and light-weighting of the harness, if separate power lines were not necessary. The new concept of Power-over-Data-Line (PoDL) supports this strategy in vehicle applications. It uses the 100Base-T1 and 1000Base-T1 interfaces to supply power parallel to the signal on a single unshielded twisted pair. TE is testing PoDL in combination with MATEnet and will validate this option within the MATEnet interconnection system. Testing so far has been very positive and indicates a beneficial use with up to 48 VDC. — A 2 B A u t o m o t i ve A u d i o B u s ® — Our MATEnet is a potential interconnection technology for the Automotive Audio Bus® (A2B), developed by Analog Devices. This digital audio bus with up to 50 Mbit (50 million bits/second) bandwidth was designed to reduce the weight of high—fidelity wiring for automobiles while significantly reducing the weight of existing cable harnesses. One potential use is multiple microphone arrays within vehicles that allow different applications such as voice recognition, active noise cancellation, and in-car communications to perform.
