FlexRay transceiver from ams gains design win
The device was selected to provide the network interface in the harsh powertrain environment because of its extremely high temperature rating. It is the only FlexRay transceiver on the market to be specified for operation at a junction temperature as high as 165°C.
The module manufacturer also requires the part to be supplied as a bare die, an option that ams is able to provide while meeting the automotive industry’s stringent quality specifications for unpackaged devices. The part is also available in an SSOP20 package qualified up to 150° ambient temperature.
The AS8222 transceiver, which provides the interface between the digital logic and the copper cable transmission lines, conforms to the FlexRay standard v2.1 rev B. With transmission rates up to 10Mb/s, FlexRay provides 20 times the speed of the unshielded twisted copper cable used in cars today. FlexRay is fault tolerant and time triggered, providing dependable delivery of messages for safety applications.
The AS8222 forms part of a family of FlexRay devices from ams addressing requirements for basic and standard transceivers, as well as for Active Star network management transceivers.
The transmission module using the AS8222 will begin volume production in Q2 of 2013, the company said.
