Crystal Quartz Resonator 1.8432 Mhz (high)

Crystal Quartz Resonator 1.8432 Mhz, (Kristal 1.8432 Mhz) common used in old computers.

UART clock allows integer division to common baud rates up to 115,200(×16×1) or 230,400(×8×1). Since older UARTs used this frequency to derive common baud rates up to 115,200, then multiples of this frequency are able to do the same, such as 3.6864 / 5.5296 / 7.3728 / 9.216 / 11.0592 / 12.9024 / 14.7456 / 16.5888 / 18.432 / 20.2752 / 22.1184 / 23.9616 / 25.8048 / 27.648 / 29.4912 / 31.3344 / 33.1776 / 35.0208 / 36.864 / ..., and is why these MHz frequencies are commonly used.
