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 application (i.
e.
, start-up).
This protected mode prevents application malfunctions from influencing the integrity of the network and the system.
The INIC includes the MOST NetServices stack’s MiniKernel, thus providing MOST compliant real time behavior.
This significantly relieves the External Host Controller (EHC) from realtime processing tasks.
D Ordering Information The OS81082 INIC50 ePHY is available as: OS81082 INIC Engineering Sample Order No.
