I'm trying to understand the Crystal oscillator circuit on the Link-it Schematic. The MT7688 documentation is pretty light on documentation about the external clock setup and I've not seen a crystal oscillator circuit like this in the past. I'm used to MPU/MCUs with an xtal_in/xtal_out and a couple of load caps.
Also I couldn't find the exact datasheet for the crystal listed. Is it a standard SMD crystal?
