Both the 455 crystal oscillator and the 455e crystal oscillator belong to the ceramic crystal oscillator, which is a piezoelectric component, similar to a quartz crystal resonator, which is actually the same product.
Both the 455 crystal oscillator and the 455e crystal oscillator belong to the ceramic crystal oscillator, which is a piezoelectric component, similar to a quartz crystal resonator, which is actually the same product. In the TV remote control, the crystal is a yellow, square, 2-pin component, model 455E, typically located near the integrated circuit. In the market, some customers will also search for 455K crystal oscillator, so what is the relationship between 455e crystal oscillator and 455k crystal oscillator? Whether their parameters are the same, here Yangxing Technology will explain to you that under normal circumstances, there will be no 455K crystal oscillator. Because the E of the 455E crystal oscillator represents a frequency range of 401~509K between the ceramic crystal oscillators. So 455K and 455e are interoperable, and it may be different in the market. (For related reading, please see YXC Yangxing** "How the Ceramic Resonator Works")
In various remote controllers, the ceramic resonant frequency is conventionally used as 455 kHz. Because the remote controller works with a certain clock source, the clock signal is divided, encoded, transmitted, and then turned into an infrared command signal. The ceramic crystal oscillator refers to the electronic component of the ceramic package that generates the resonant frequency. It functions as a frequency generator and has stable and anti-interference performance. Widely used in various electronic products, it has lower frequency accuracy than quartz crystal resonators, but its cost is lower than that of quartz crystal resonators. It plays an important role in frequency control. All electronic products require resonators for frequency transmission and reception. .
Whether the crystal oscillator of the remote control is damaged or not, it is necessary to use a digital multimeter with a capacitance measurement file to measure. First, measure the resistance to infinity with the last ohmic file, and then use the lowest capacitance file to measure the capacitance should be about 250P--320P, otherwise it is good. bad.
