I'm using a microcontroller board with 8 MHz ceramic resonator(3 legs). However, the frequency of the resonator does not allow me to achieve a baud rate of 115200bps. Therefore, i need to replace it with a 7.3728MHz ceramic resonator (3 legs) in order to get the 115200bps baud rate. Sadly, i was unable to found the 7.3728MHz ceramic resonator but i did found quartz crystal (2 legs) with 7.3728MHz frequency. I was told that if i replace the ceramic resonator with the quartz crystal, i need to include 2 capacitor, C1 and C2. However, how do i know what the value of capacitor that i need to use? Please help! If there is better solution, please let me know.
