WebDec 20, 2024 · I've spent quite a bit of time read up on oscillator circuits and trying to get this circuit to oscillate. I'm trying to build this oscillator for a clock but I won't be putting it into a RTC, so I only need the 32.768 kHz frequency as an output. Rereading, I'm pretty sure I need 25 pF caps instead as I misinterpreted how load capacitance worked. WebCrystal Tester. My version of a crystal tester. And circuit board for the project.
