Hi

I'm working on a audio project using the I2S bus which has to run on a external XTAL but is it possible to mount a XTAL on a CY8CKIT-014 kit? I have seen additional App.notes about the subject but no one seem to consider the CY8CKIT-014 kit.

Thanks

Plainly: No! When you compile an example - project on a -14 kit, there is a note telling you that the board uses x-tal pins for I/O (I think the accellerometer is connected to those) and that this will not be allowed for future releases of the PSoC5. This seemingly announces that the two pins to connect a crystal to are alredy used on the board.

Let me offer you my version.
I have this working for a long time.
I hope everything is clear without translation.

You could always hack the board to do it, then restore hack after you

have done by cutting traces and adding pins to jumper. Pins could be

added at accelerometer pads to give support, while cutting or lifting the

lead on the accelerometer.

I checked 68013. Contact CLKOUT has a frequency 48MHz. XTAL may not be greater than 25 MHz.
But you can deceive Configure System Clocks and assign Freq: 24 MHz. This will work.
But my mom said that the cheat  (too often) is not good :))))
 

 I dont have a -14 kit  to test. But if Pavloven is right about the CY7C68013A output a 48MHz clock on clkout, then it can be wired to a IO pin  and then used as a 48MHz digital signal source for the IMO.

attacked pic to show it

In the previous picture I forgot to select the  "Digital signal" option in the IMO, but you get te idea

Variant with an external frequency to 40 MHz I have worked:

But if I connect P5[7] and TP2 (CLKOUT) is not working....
 

OK. All works. I forgot to install: Sync MOde: Transparent
I will Add this to my site, if you don't mind.
