New MB88387 Integrates 1394b PHY, Link Layer, Copy Protection Functions
Fujitsu Microelectronics America, Inc. (FMA) today introduced a new 1394 controller, the world's first IDB-1394-compliant (Intelligent Transportation System Data Bus-1394) physical
and link layers with integrated 1394 controller.
The new MB88387 from Fujitsu is designed for in-vehicle audio-video multimedia entertainment systems. It connects top-quality video and audio to vehicle displays from their head unit, DVD player, navigation, camera,amplifier or other devices. The MB88387 incorporates both the 1394b PHY and Link in a single chip, along with the digital transmission content protection
(DTCP) standard that prohibits unauthorized copying or transmission of protected A/V content. The controller supports IEC61883 AV protocols for smooth audio and video stream playback.
The MB88387 conforms to the IDB-1394 standard developed jointly by the IDB Forum and the 1394 Trade Association, which is the optimal vehicle network for transmission of digital content such as DVD video and digital television in cars, trucks and SUVs. The chip supports data transfer rates up to 400Mbps. It operates at 3.3V (I/O) with internal voltage of 1.8V. The PHY layer supports two 1394b/S400 ports, and the integrated DTCP function allows encryption or
decryption of two data streams at the same time. Systems networked using the MB88387 can transmit audio and video throughout the vehicle at distances up to 100 meters.
"Multimedia entertainment systems are one of the most exciting advances in new vehicles, and automakers worldwide are beginning to develop them now," said Akio Nezu, senior marketing manager for Embedded Products for Fujitsu
Microelectronics America. "This new, fully-integrated controller with the 1394b PHY designed in incorporates all of the advanced technology required to implement state-of-the-art audio-video multimedia systems safely and
effectively in cars, trucks and sport utility vehicles. We also understand that IDB-1394 will take important roll on active safety system with its video or camera data transfer capability."
To implement transmission of navigation video and camera video for monitoring of the traffic environment, Fujitsu is continuing to develop
products based on the IDB-1394 standard as part of the company's technical road map.
