Hello, thank you for responding to my post. This is my first PSOC design and I am not too familiar with the Clock Tree. I learned that you must double click in the Clocks to get the Configuration Window to appear. I disabled the XTAL and checked the Digital Signal Block. I don't know what to enter in this box I clicked the ellipse and picked the first item in the list. I enter the clock frequency of 25Mhz.
Here is my view.
I'm not sure that I'm doing things right here. How do I tell the system that there is a 25Mhz clock on pin 43? What should show up in the Digital Signal Block for the Name edit box?
You are routing an external clock through the ECO pins. So you have to enable the XTAL and XTAL 32KHz block in the clocks tab instead of Digital Signal block. So please disable the "Digital Signal" block and enable "XTAL" block.
Once you check the blocks configure the clocks according to the specifications.
Please refer the below application note for detailed information.
Hello, thank all for the quick responses. I implemented your suggestions.
How does this look so far. I'm a little confused with the instructions at Oscillator digital clock on ECO input pins . They suggest, "So summary is MHz ECO needs to be disabled and the same input pin can be used to give external digital clock. But KHz ECO needs to be enabled and connect external clock to the input pin of KHz ECO in PSoC."
How do I disable the MHz ECO? I thought this was done by not checking the XTAL block. Also, how does the system know that I'm not using a Crystal? Isn't it expecting a crystal connection?
Can you help explain this?
P.S. I'm using a MEMs oscillator because the environment in which this board will be placed has lots of vibrations.
Hello, I haven't heard back from anyone on this post. I still need some help. If anyone has done this before can you please let me know if my setup is correct?
