Resistor buffering of the clock lines
The 22 kHz doesn’t make the PCB layout a transmission line. It’s the rising edge of the 22 kHz signal. If you have a really fast rise time then you could get reflections and you need to treat the circuit as a transmission line. If you just have a point to point a resistor at the output is...- brandoni
