Programmable crystal oscillators are mostly active crystal oscillators composed of two chips: a full silicon MEMS resonator and a chip with temperature compensation function that can start the phase-locked loop CMOS circuit. It is packaged in a standardized semiconductor chip MCM package. A programmable crystal oscillator is a blank crystal oscillator to which the parameters of your crystal oscillator, such as frequency deviation, operating voltage, load capacitance, frequency, etc., are provided to the crystal oscillator manufacturer. Manufacturers can program these parameters through devices such as computers, coupled with a programmable crystal oscillator test fixture, to write these parameters into the blank crystal oscillator.
Supports any frequency point from 1-800MHz, with precise output to 5 decimal places (e.g. 65.53500MHz). Supports multiple operating voltage matches such as 1.8V, 2.5V, 2.8V, 3.3V! Supports various accuracy matches such as 10PPM, 20PPM, 25PPM, 30PPM, 50PPM, etc.! International standard QFN package 33607050, 5032, 3225, 2520 programmable crystal oscillators are suitable for clocks, digital products, car audio systems, mobile phones, walkie-talkies, digital cameras, MID tablets, optoelectronics, and various communication equipment such as variable frequency speed control devices.
A programmable crystal oscillator test fixture is an auxiliary device used to test and verify during the programming process of a programmable crystal oscillator. Its role is to ensure that the programmable crystal oscillator can work normally after programming is completed and to effectively detect the parameters and performance of the crystal oscillator. In the programmable crystal oscillator programming process, the crystal oscillator test fixture has the following advantages:
Efficient performance verification: The crystal oscillator test fixture can comprehensively test the performance of the programmable crystal oscillator, including parameters such as frequency accuracy, temperature stability, voltage adaptability, etc., to ensure the quality and reliability of the crystal oscillator.
Automated testing: Crystal oscillator test fixtures are usually equipped with automated testing functions, enabling fast and accurate large-scale testing, thereby improving production efficiency and product consistency.
Fault diagnosis: If problems are detected in the crystal oscillator during programming, the crystal oscillator test fixture can help locate the faults and provide detailed test reports for subsequent maintenance and adjustments.
By combining the crystal oscillator test fixture with the programming process of the programmable crystal oscillator, production efficiency can be effectively improved, product quality ensured, and production processes simplified.
