MOST Networking Solution Adopted in Third Lexus Platform
SMSC, a leading semiconductor company that provides Smart Mixed-Signal Connectivity solutions, announced that its Media Oriented Systems Transport (MOST) networking technology has been selected as part of the infotainment system for the new Lexus HS250h, which is distributed in the U.S. and Japan.
We are pleased to see the rapid roll-out of MOST in the car models of Lexus, said Dr. Christian Thiel, General Manager of SMSC's Automotive product line. With the RX and IS having been released earlier, the HS is the third Lexus model that has been launched with MOST this year. In addition to Lexus, MOST is already in use in six Toyota branded models, including the new Prius. A key reason for this fast roll-out is that MOST50 allows the use of copper cables, which enables a plug-in, component approach with existing manufacturing processes.

MOST multimedia networking technology enables the networking of feature-rich infotainment systems in automobiles by providing the means to distribute multimedia entertainment functions among the various control devices around the car. For example, a CD changer, radio, global positioning system, mobile telephone and DVD player can be established in an efficient ring network and can send crisp, static-free audio signals digitally to the amplifier by utilizing the MOST network.

MOST50 uses a double density coding scheme to double the bandwidth over the first generation, MOST25, while maintaining the same physical transmission frequency. With MOST50, the data signal is transmitted over Shielded Twisted Pair (STP) or even Unshielded Twisted Pair (UTP) copper cables, allowing customers to use conventional wire harness and established manufacturing processes.
