LP19BF33IET

LP19BF33IET Application Field and Working Principle

LP19BF33IET is a crystal oscillator with a frequency range of 32.5k-375kHz and a frequency tolerance range of ±20 ppm or ±50 ppm at 25°C. It is often used in applications such as time and frequency control, precision clock oscillator, RF frequency synthesis and low power communication. The reasons why LP19BF33IET is so popular are that not only is it highly reliable, but require no external components, making it a highly efficient device.

Working Principle

LP19BF33IET use an AT-cut quartz crystal as their resonator. As the name implies, this type of crystals is cut at an angle from the normalized ‘z’ direction. The application of the electromechanical behavior of quartz crystal, the device will result in the conversion of electrical energy into mechanical energy and generate a small sine-wave signal voltage based on the frequency of the device. This is the fundamental principle of operation for the LP19BF33IET crystal oscillator.

The resonance frequency of the crystal is determined by the physical structure of the crystal itself, and must be kept in a temperature range of between -40°C and +85°C. LP19BF33IET use a Clipped Sine Drive circuit that helps provide a wide operating temperature range and high-frequency stability.
