Crystals

LP143F33CDT, a type of quartz crystal manufactured by company LP, is a programmable quartz crystal unit (also known as a clock oscillator) used in radio frequency and timing applications. It features clock frequencies from 1 MHz to 33 MHz and is useful for applications ranging from audio frequency circuits to microcontrollers. The LP143F33CDT has a variety of features that make it attractive for many applications, such as a height of only 1.2 mm, an operating voltage of 2.5 – 5.5V, a frequency stability from ±30 ppm to ±15 ppm, and a high operating temperature range from -20°C to +85°C.

Application Field

The LP143F33CDT is used in a wide range of electronic devices. It is often used in digital cameras and computers to provide the time and date information that is used to set the time and date functions. It is also used in audio frequency circuits, such as digital music players, to balance the audio frequency as well as provide clocking functions. Furthermore, the LP143F33CDT can also be used in microcontrollers such as the Arduino and PIC processors to provide clocking functions.

Working Principle

The LP143F33CDT is a quartz crystal unit with a frequency range from 1 MHz to 33 MHz, with a frequency stability from ±30 ppm to ±15 ppm. The unit contains a quartz crystal, which is a piezoelectric device that vibrates at a specific rate when an electrical voltage is applied. This rate is known as the “resonance frequency”, and it is determined by the dimensions and shape of the crystal. The LP143F33CDT uses this resonance frequency to generate a steady oscillating electrical signal that is used for timing and clocking applications.

The LP143F33CDT also has an “accuracy range”, which is the difference between the unit’s tolerance and the actual frequency variation over time. In order to maintain a stable oscillation frequency, the unit requires an external circuit to detect any changes in the oscillation frequency and adjust the frequency accordingly. This circuit is known as the “programmable oscillator”, and it must be programmed to the desired frequency when the LP143F33CDT is installed.
