TIOL112: support the IO-link without needing an external clock

Hi Wouter,

I'm not sure I understand what you are asking.  The TIOL112 is a simple transceiver that translates the digital signals from the microcontroller and the IO-Link cable.  It does not need an external clock because all the signals are generated in the microcontroller.  However, the microcontroller may need an external clock source, but this question is not directly related to the TIOL112.

Hi Jonathan,

Thank you for the response.

Indeed it is not directly related to TIOL122, I was not able to ask the question without putting in a component.

I am wondering if we have IO link component that have their clock integrated, such that it does not need an external clock, not from a MCU orso.

Kind regards,

Hi Wouter,

Typically there is an MCU running an IO-Link Protocol Stack combined with an IO-Link transceiver to handle the analog PHY aspect of the communication.  We don't have a single integrated device and all of our IO-Link transceivers would require an MCU which I would expect requires an external clock.  However, my expertise is with the TIOL112 and not with our MCU portfolio, so I don't know if there is an MCU option that had an internal clock source and would meet the IO-Link firmware requirements.
