The integrated electrical physical layer (ePHY) signal conditioning circuitry offers differential I/O that directly interfaces to a passive ePHY transformer. This enables MOST data transmission via unshielded twisted pair (UTP) cable. The INIC provides full encapsulation of all functions necessary to develop a MOST compliant device. It allows an easy implementation of MOST into a device. The INIC also provides supervision of the application, and a protected mode is entered during malfunction or absence of an app...
