Hello,
I am using a clock generator (Si5351 from Adafruit) to generate a signal of custom frequency. The output frequency is controlled by an Arduino UNO and it goes to the XTAL1 pin of another Arduino UNO. The problem is that the output frequency has an amplitude of only 3.3V, which is not enough for the other Arduino to work properly. I talked with a guy who did a similar project and he told me to build a "buffer" to increase the signal's amplitude. He gave me some instructions, but I am not experienced enough to understand how I am supposed to connect the components. Here are the instructions:
Use a single inverter to build a buffer. I need to "capacitefy" couple input signal via a capacitor and then take restored signal from the output. He recommended the 74AC series inverter.
So what do I have to do? Which wire I connect where? A schematic would be perfect.
Thanks in advance.
