How to set 20mhz oscillator crystal to 4mhz
WebThe transistor, a 2N4265 is a general purpose NPN transistor connected in a common collector configuration and is capable of operating at switching speeds in excess of 100Mhz, well above the crystals fundamental frequency which can be … WebThis can be used to divide to get all sorts of lower frequencies, i.e. 4 / 2 = 2.00 MHz 4 / 3 = 1.33 MHz 4 / 4 = 1.00 MHz 4 / 5 = 0.80 MHz and so on… So with the above in mind, I modified the 4 MHz Colpitts Oscillator to look like this: Download The CADSoft Eagle schematic here

For using this option, first set the configuration bit for clock selection as HSPLL. The PLL prescaler divides the clock to get the 4MHz input to the PLL. The value depends on the oscillator. For 20MHz oscillator, it is 4.
WebDec 9, 2006 · Since each resonator/crystal has its own characteristics, the user should consult the resonator/crystal manufacturer for appropriate values of external components, or verify oscillator performance. Crystal manufacturers typically rate their crystals to operate closest to the specified frequency if they have a load capacitance of 20 pF to 30 pF. WebMar 9, 2013 · i have got a 20MHz crystal and while reading the datasheet i have learned i need to connect it to the xtal1 and xtal2 pins of the uC. and i know that i need to use 22pF capacitors on both pins and then put them to ground... But i dont know the part where i need to tell the uC that it has to work off the external clock
