Hello,
I'm considering using the PSOC5LP in my design.
One of the requirements is clock synchronization, i.e. I need to apply an external clock into the PSOC (and other devices) from external external PLL device.
I saw that there is an option to apply an external XTAL ('MHzECO').
Is it posiible to apply just a Clock signal (say LVDS/LVPECL logic level), without using a XTAL?
Thanks!

MaPo,
In short, the answer is YES.
In order to use an external clock as an input source, you need to:
- Allocate an input pin to use on the TopDesign. Give it a net name such as "ext_clk"
- Open the DWR with the Clocks Tab and Edit Clock...
- Select the following in this order shown in the pic below.
I hope this helps.
