This frequency is the standard PC AT master clock used as the reference for video timing, PCI bus generation, and system timer circuits in PC-compatible systems. Divided by 3, it yields 4.77MHz (original PC clock); multiplied or divided further, it generates standard VGA pixel clocks and USB timing references. The compact 3.2x2.5mm SMD package suits space-constrained embedded PC designs.","working_principle":"The oscillator integrates a quartz crystal tuned to 14.31818MHz with a CMOS maintenance circuit. The 14.31818MHz frequency was chosen as the PC AT master clock because it can be divided by 3 to yield 4.77MHz (original PC clock), divided by 12 for 1.19318MHz (8254 PIT timer input), and multiplied by various ratios to generate VGA pixel clocks (25.175MHz, 28.322MHz). The CMOS output provides a clean square wave suitable for clocking digital logic and PLL reference inputs.","pin_description":"
