Good Clock Waveform

Hello,

I keep seeing issues with Clock waveforms so thought I would post a scope plot from my board at that stage.

Please note that I've limited the bandwidth to 20MHz to simulate what a low cost scope may show.

Cheers,

Richard

It doesn't look much square.
If U1 is replaced from a 74HCT04 to a 74HC04 I think you can get a better square wave.

It looks how it should be. Symmetrical would be nice for Justin's high resolution mode. But I haven't looked after the 74HC04 issue any further.
