Input a crystal oscillator to exco.eco_in for PSoC4100S Plus

[YoIs_1298666]

Hello,

I later realized that EXTCLK could not be entered into the PLL.

Eventually, a crystal oscillator will be connected to the ECO.

Regarding the current situation, is it possible to input a rectangular wave of a crystal oscillator with the same amplitude as the power supply voltage of the PSoC 4100S Plus to exco.eco_in on P0.6?

Best regards,

Hello,

Generally, We think that We can connect it without any problem.
Should we change the question from community to CASE because our customer is in a hurry?

Best regards,

Yocchi:
Yes. You can drive a clock to P0.6, this is one of the intended uses of the pin. I have done it on several different PSoC4 parts. To use this clock, it must be selected in the clocks page of the DWR.
