Microchip Technology has announced that its MOST50 Intelligent Network Interface Controller (INIC) will power the infotainment system of Toyota Motor Corporation ’s new Lexus GS luxury sedan series. The new GS series is Toyota's latest brand to use these devices in its infotainment systems. Lexus GS is using the company's OS81092 INIC. The automaker is one of more than 30 manufacturers that rely on Media Guided System Transmission (MOST) technology to transmit video, audio, data packets and control data throughout the vehicle.
Dan Termer, vice president of automotive information systems at Microchip, said: "Audio quality is very important for Toyota, as Toyota promotes the Lexus GS audio system as" the quality of home audio systems at home and away from home. " It is implemented as a pure digital audio transmission at the receiving end, and it is cost-effective to allow simultaneous audio transmission and control via a single cable. "
The company's MOST technology has been used in more than 200 car models worldwide, and its ePHY has features optimized for UTP copper wires. As a result, the system can use dedicated channels to minimize processor overhead in the main infotainment control unit without the need for a time synchronization protocol to predict and efficiently transfer video, audio, data packets, and control data.
MOST INIC also provides industry-standard hardware interfaces for processors and peripherals to achieve efficient routing of information, which greatly simplifies module design. Thanks to MOST INIC's ultra-fast network startup capability, end users can immediately use the vehicle's infotainment system.
To facilitate development, MOST technology comes with a complete tool, software and support ecosystem: tool vendors include K2L's OptoLyzer MOCCA series and OptoLyzer Studio; software stacks can be MOST Linux drivers, MOST NetServices or DTCP-Stack; provide schematics And layout review, such as MOST Check; multimedia supporting IC products include video encoding, DTCP content protection, I / O extension and power management.
