Performance Summary - Analog Devices LINEAR TECHNOLOGY LTC2874 Demo Manual

Description
Demonstration circuit 2228A is a complete 8-port IO-Link
Master that uses two
its IO-Link v1.1 physical interface (PHY). DC2228A
operates either with an external supply V
over Ethernet (PoE) system. The IO-Link stack protocol
runs on an NXP microcontroller. A software Control Tool
operates the DC2228A.
