IO-LINK PHY for Device Nodes
SN65HVD101/2
The SN65HVD101/2 IO-LINK PHYs implement the IO-LINK interface for industrial
point-to-point communication. When the device is connected to an IO-Link master
through a 3-wire interface, the master can initiate communication and exchange data
with the remote node while the SN65HVD10X acts as a complete physical layer for the
communication.
TheIO-LINKdriveroutput(CQ)canbeusedinpush-pull,high-side,orlow-sideconfig-
urations using the EN and TX input pins. The PHY receiver converts the 24-V IO-LINK
signal
ontheCQpintostandardlogiclevelsontheRXpin.Asimpleparallelinterface
is used to receive and transmit data and status information between the PHY and the
local controller.
