The MIPI Alliance has released MIPI A-PHY v2.0, an updated version of its automotive high-speed asymmetric serializer-deserializer (SerDes) physical-layer interface. This new version increases the maximum downlink data rate to 32 Gigabits per second (Gbps) on a single channel, doubling the previous capacity. It also introduces an additional uplink gear supporting up to 1.6 Gbps, an eight-fold increase in […]

10Base-T1S simplifies automotive zonal architectures
By Andreas Pellkofer and Madhura Deyanda Poonacha, Analog Devices Automakers aim to provide vehicles with home-like comfort and entertainment, which raises demand for electronic control units (ECUs). Older bus technologies and electrical/electronic architectures struggle to keep up. 10Base-T1S Ethernet is transforming cars into fully connected experiences. Automotive electronic control units (ECUs), which control each component […]
10Base-T1S/L connects sensors in cars and buildings
IEEE 802.3cg defines these two Ethernet flavors, which deliver data and power over a single pair of wires. In 2019, IEEE published 802.3cg, which added clauses 146 and 147 to its Ethernet 802.3 standard, which created 10Base-T1S (short reach) and 10Base-T1L (long reach). These two Ethernet flavors can serve vehicles and industry, respectively, where few […]

Digital radio processors demodulate and decode up to four channel
Skyworks Solutions, Inc. introduced the Si469xx family of automotive digital radio coprocessors for future in-vehicle infotainment (IVI) systems. With its combination of integration, flexibility, and low cost, the Si469xx family of coprocessors is optimized to operate with Skyworks’ Si479xx Hybrid Software Defined Radio (SDR) Tuners to achieve a cost-effective digital radio receiver. The new Si469xx product family […]
What inductor characteristics are needed for PoDL in Single-Pair Ethernet?
Basic Single-Pair Ethernet (SPE) requires at least a common mode inductor (CMI). When power over data line (PoDL) functionality is added, so is a differential mode inductor (DMI) and sometimes an isolation transformer. These magnetic elements interact and can reduce SPE performance. Correctly specifying them is important to ensure efficient operation and reliable data transfer. […]
