The sales team of Hefei Minghua Shang Electronics Co., Ltd. has been deeply involved in the crystal oscillator industry for over two decades, providing comprehensive solutions and technical support for crystal oscillators. Meanwhile, it offers frequency compensation solutions (such as adjusting the load capacitance or frequency center value) to adapt to different application scenarios. SIWARD Crystal is a globally leading provider of quartz frequency control component solutions. It was established in 1988 and focuses on the R & D, production, and sales of quartz crystals, oscillators, and filters. The resistance of thermistors (such as NTC) decreases as the temperature rises, while that of PTC is the opposite. After this change is converted into an electrical signal, it is input into the processor through analog - to - digital conversion (ADC). The processor calculates the correction amount according to a preset algorithm (such as the temperature - frequency compensation model), and then outputs a control signal through digital - to - analog conversion (DAC) to adjust the output frequency of the crystal oscillator.
Compensation methods can be divided into two categories: analog (such as varactor diode tuning) and digital (such as MCU algorithms). The latter has higher accuracy.
The key performance depends on the consistency of the F(T) curve of the thermosensitive element, especially the strict control of temperature measurement coefficients (such as T0 and A1 parameters).
Main technical parameters
Package size: Common SMD models include 3225, 2520, 2016, 1612, etc., meeting the miniaturization requirements.
Frequency range: Typical frequency points cover 19.2MHz, 25MHz, 26MHz, 38.4MHz, 52MHz, 76.8MHz, etc.
Temperature range: It supports multiple ranges such as - 40℃ to 85℃, - 40℃ to 105℃, - 40℃ to 125℃, etc., adapting to industrial - grade environments.
Frequency stability: The deviation can be controlled within ±1ppm to ±5ppm in a wide temperature range, significantly better than ordinary crystal oscillators (usually more than dozens of ppm). Product features and applications: Small size, high stability and reliability, low equivalent resistance, and can be widely used in industrial electronic equipment and instruments.
