Web2 days ago · With a clock of 19.2 instead of 20Mhz it's not possible to run at either of those clocks speeds. The closest would be 163.2 or 201.6. So how would I tell flexprop that I have a 19.2 instead of a 20Mhz crystal so that I can get one of those frequencies otherwise my compile will run at 192Mhz instead of 200Mhz or 153.6Mhz instead of 160Mhz. Another useful crystal oscillator is the overtone oscillator shown in the schematic below. Standard-cut crystals are difficult to make; higher than 20MHz as the wafer of quartz becomes too thin. A solution to this is to use an overtone oscillator. An example is the frequency source for a 144MH transmitter.
