Applications

The 638P15623C3T model oscillator is a small size, surface mount type SMD crystal oscillator, which is suitable for various types of communication and signal processing chips in consumer electronics, and provides stable and reliable timing and frequency signals.It can be widely used in various portable electronic devices such as digital TV boxes, set-top boxes, Tablet PCs, PC tablets, HDPDs, DVD/DVCD, satellite receivers, Set boxes, mobile phones, Bluetooth, notebooks and other mobile devices. And the temperature range of the oscillator is -40°C to +85°C.

Working Principle

The 638P15623C3T oscillator is a compressor-type oscillator. It provides a stable, transformable and precise frequency signal output and is highly compatible. The core component of the oscillator is a quartz crystal. When the quartz crystal is supplied with a minute DC electric field, it vibrates at its natural resonant frequency to generate an AC signal. This AC signal is then amplified through a transconductance amplifier and appears at the output terminals as a sinusoidal waveform. The frequency and stability of the output signal depend primarily on the characteristics of the quartz crystal used.

The 638P15623C3T oscillator is suitable for high-speed signals because its output amplitude & low jitter is relatively small. It is composed of a quartz crystal and a circuit composed of inductance, capacitance and resistance. The quartz crystal is a nonlinear dielectric material, and its electrical properties depend on its temperature, mechanical stress or electric field. When the applied voltage V is small, the Q value does not change much in the crystal. When the applied voltage e reaches a certain level, the variation of the Q factor oscillates, and this oscillation is the oscillation of the crystal. The frequency of the output signal of the oscillator is determined by the frequency of the crystal oscillator circuit.

In conclusion, the 638P15623C3T oscillator is a small size, surface mount type SMD crystal oscillator, which is suitable for various types of communication and signal processing chips in consumer electronics. It can be widely used in various portable electronic devices such as digital TV boxes, set-top boxes, Tablet PCs, PC tablets, HDPDs, DVD/DVCD, satellite receivers, Set boxes, mobile phones, Bluetooth, notebooks and other mobile devices. The frequency and stability of the output signal depend primarily on the characteristics of the quartz crystal used. Its output amplitude & low jitter is relatively small and makes it suitable for high-speed signals.
