Why is 22.1184 MHz a popular frequency?
With a 16x clock, 22.1184 MHz divides exactly into standard UART baud rates such as 9600, 19200, 38400, 57600 and 115200, which keeps baud-rate error at zero. It is widely used in microcontroller serial projects for this reason.
Which load capacitors are needed for this crystal?
Use two capacitors from each crystal pin to ground, sized for a 20 pF load. A common starting point is C ≈ 2 × (20 pF − stray capacitance), usually around 30 pF each. Verify against your microcontroller's oscillator guidance.
