What are the crystal oscillator frequencies?
Thread Content
Crystal oscillators are widely used in electronic components and accessories; for example, they are found in keyboards, motherboards, mice, and so on. Let’s take a look at what crystal oscillator frequencies are required for these electronic components Motherboard: 14.318MHZ, 24.576, 25MHZ, 27MHZ, 32.768KHZ Display: 8M/14.31818MHZ, 12.000MHZ, 24.000MHZ, 28.224MHZ Hard drive: 23.040MHz, 28.224MHz Optical drive: 33.8688MHz, 16.9344MHz, 18.432MHz Keyboard: 6.000MHz Mouse: 6.000MHz, 12.000MHZ, 24.000MHZ Webcam: 12.000MHz Bluetooth: 16.000MHz Wireless WIFI: 25.000MHZ 2.5G/3G (40.000MHz, 44.000MHz) ADSL for network transmission: 12.288MHz, 35.328MHz, 50.000MHz The crystal oscillators on the motherboard are mainly categorized as follows: Crystal oscillator connected to the chip – frequency clock crystal oscillator chip: 14.318MHz Real-time crystal oscillator – Southbridge: 32.768KHz KBC: 32.768KHz Network card crystal oscillator – Network card chip: 25.000MHz Sound card crystal oscillator – Sound card chip: 24.576MHz Graphics card crystal oscillator – Graphics card chip: 27MHZ Card reader crystal oscillator – Card reader chip: 12MHz The most important crystal oscillators on the motherboard are the real-time crystal oscillator and the clock crystal oscillator; the real-time crystal oscillator provides the oscillation frequency for the southbridge, while almost all frequencies on the motherboard are based on the clock crystal oscillator. If they are damaged, the motherboard cannot function properly. The crystal oscillator, along with clock chips, sound card chips, network card chips, graphics cards, and other chips that form oscillation circuits, constitute the most important source of clock signals on the entire circuit board.
