LP040F35CET Application Field And Working Principle

LP040F35CET is a type of crystal oscillator used extensively in electronic circuits. It uses quartz crystals to produce a steady frequency output. The frequency of the oscillator is determined by the cut of the quartz crystal. This crystal is made from a specialized low-frequency quartz crystal, which is known for its stability and accuracy. The frequency stability is guaranteed over a wide range of operating temperatures and environmental conditions.

The LP040F35CET is a general-purpose miniature or miniaturized SMD crystal oscillator available in thru-hole, 4 pin, and 5 pin packages. This crystal is highly suitable for applications such as phase-locked loops, radio receivers, phase shifters, and pulse width modulation (PWM) circuits. It has a total frequency stability of ±30 ppm (-20°C ~ +70°C). The frequency characteristics also include high frequency stability at high temperature and a low jitter value.

Working Principle

The LP040F35CET crystal oscillator is based on the principle of quartz vibrating at an extremely precise frequency. The resonant frequency of the quartz crystal is set during manufacture by the process of lapping and polishing the quartz with an abrasive, then tuning the quartz with a hydrophone. The frequency of oscillation is determined by the physical characteristics of the crystal, including its size and shape, and with the addition of an applied voltage, the crystal will begin to vibrate very rapidly.

The application of this frequency depends on the type of circuit implemented. In an analog circuit, the oscillator frequency is typically fixed since no voltage control input is applied. In a digital circuit, a voltage control input is usually employed, so the frequency can be adjusted through the use of a voltage divider.

Applications

The LP040F35CET crystal oscillator is used to produce a very stable signal or clock for a wide range of applications including wireless communications, medical equipment, electronics test and measurement, automotive, aerospace, and radio frequency identification (RFID) systems. It is also used in data transmission and signal processing in a variety of industrial and consumer products such as personal computers, modems, cellular phones, digital audio players, and other applications that require very precise signal timing and frequency stability.

LP040F35CET has been carefully designed for use in a wide range of applications, with features such as a wide operating temperature range, high frequency stability, high accuracy, and low jitter values. It is ideal for use in applications that require precise signal timing and frequency stability, such as data transmission and signal processing, wireless communications, electronics test and measurement, and high-end consumer electronics.
