Hi,

I was trying to find on the datasheet, but I was not able to locate it.

What's the output impedance of SAK-TC387QP-160F300S AE?

It's possible to configure the pin to already have 50 ohms internal impedance or select specific impedance?

I'm looking for this value to right design Spi, clks, i2c and fast switching tracks on the project.

 

Thank you.

Hello,

Please refer the  RDSON parameter specified in the datasheet.

Thanks.

Ok, so for this uC is in the range of 31-80 ohms with typical 55ohms.

To avoid ringings, the recommendation of Infineon is to control the trace as 50 ohms and not use resistor or control the impedance in the range of 100ohms with external resistor to minimize error?
