Building a MOST150 Network Using a Daisy Chain Configuration
Used by major OEMs in over 200 vehicle models

Microchip Technology Inc. announced the availability of its latest MOST150 Intelligent Network Interface Controller (INIC).

This product enables automotive manufacturers and Tier 1 suppliers to integrate MOST ^® (Media Oriented Systems Transport) networks in both ring topologies and daisy-chain configurations over a coaxial physical layer supporting full-duplex communication.

Full-duplex daisy-chain networks allow two adjacent devices on a network to be connected with a single cable, reducing the number of cables and connectors required for reverse channels on each network.

Microchip's OS81119 INIC can simplify the network architecture of automotive infotainment systems by using a coaxial physical layer (cPHY), an optical physical layer (oPHY), a daisy-chain topology, or creative hybrids of the two. Additionally, customers currently using MOST150 systems can quickly migrate to new topologies or add daisy-chained nodes with little or no hardware or software redesign.

“In an industry first, customers can now build a MOST150 network using a daisy-chain configuration,” said Dan Termer, vice president of Microchip’s Automotive Information Systems business unit. “MOST networks are a proven standard used by every major OEM in more than 200 vehicle models, and this new device is the culmination of continued innovation that makes MOST an even more cost-effective technology.”
