Ethernet comes to ADAS with megapixel camera

November 17, 2014 // By Julien Happich
At electronica, Micrel together with Silicon Micro Systems announced a brand new HDR-CMOS megapixel Ethernet camera for automotive and industrial systems.

The production-ready camera is designed and manufactured by camera specialist SMS (Silicon Micro Sensors GmbH a daughter of First Sensor) and features Micrel's unique low emissions networking solutions.

“The consensus in the automotive industry is that it is only a matter of time before all networking in the car is done with Ethernet, with data throughputs of 1Gbit/node” told us Mike Jones, Micrel’s Marketing Director. “BMW was first to bring Ethernet networking into the car, it is not a question of if, but when the others will follow, especially for multiple networked cameras”, he added.

According to Jones, in the long run, Ethernet will inevitably replace MOST and FlexRay for audio and video bridging and for time-sensitive networking, simply because the standard is more open and the tools are more accessible.

The camera, part of First Sensor’s Blue Eagle’s line, features light sensitive, high dynamic range (>100dB) and wide field of view (>190 degrees). It is aimed at applications such as surround view and blind spot detection for automotive and industrial machine vision. The camera exhibits excellent resistance against harsh environmental conditions like mechanical shocks and vibrations, with a dust and water tight housing according to IP68/IP6k9k.

The Megapixel Ethernet Camera is just 26mm3 in size and significantly reduces cable harness costs by providing both Ethernet data transmission and power over the same low-cost unshielded twisted-pair wiring. It is based on Micrel’s new Quiet-WIRE IEEE standard Ethernet transceiver technology for reduced electro-magnetic emissions, it features IEEE 802.3az Energy Efficient Ethernet support, sub micro Amp standby power consumption with signal detect activation and fast link up.

In addition, one of Micrel’s high voltage synchronous switching regulators, featuring HyperLight Load and Hyper Speed Control architecture, provides all the capabilities of Power over Ethernet (PoE) without incurring any additional system cost.
