Several Knowledge Points about Programmable Crystal Oscillator Chips
What is a programmable crystal oscillator? Programmable crystal oscillators are mostly active crystal oscillators, consisting of two chips; one is an all-silicon MEMS resonator, and the other is a chip with a temperature compensation function that can start the circuit phase-locked loop CMOS. It uses standardized semiconductor chip MCM packaging. Fully automated standard semiconductor manufacturing processes can be used, such as ICs used in current electronic product design, which have very good stability and quality; human errors cannot occur during the production process.

A programmable crystal oscillator has a nice name: silicon crystal.
Generally speaking, a programmable crystal oscillator provides your crystal oscillator parameters, such as frequency deviation, operating voltage, load capacitance, frequency, etc., to the crystal oscillator manufacturer. Manufacturers can program through computers and other equipment and press the OK button to write these parameters into the blank chip.
Usually, the production lead time is 1-3 days. We know that for conventional passive crystal oscillators or active crystal oscillators when the wafers are in stock, the production lead time is 2-3 weeks, the regular lead time is about 4-6 weeks, and the special period is 2-3 months.
Therefore, in terms of lead time, programmable crystal oscillators not only have advantages in lead time but also in frequency. Functionally, the problem of temperature drift is eliminated.
Fully automatic semiconductor technology (chip level), no air tightness issues, no vibration! Integrated temperature compensation circuit, no temperature drift in the whole temperature range, -40~85℃ full temperature guarantee; mean time between failures (MTBF) up to 500 million hours! Low jitter, low power consumption, high temperature, high pressure, high humidity, and good earthquake resistance.
Supports any frequency point from 1-800MHZ, accurate output to 5 decimal places. Such as: 65.53500MHz). Supports multiple working voltage matching of 1.8V, 2.5V, 2.8V and 3.3V! Supports 10PPM, 20PPM, 25PPM, 30PPM, 50PPM and other precision matching! International standard QFN package 33607050, 5032, 3225, 2520 programmable crystal oscillator is suitable for communication equipment such as clocks, digital products, car digital, mobile phones, walkie-talkies, digital cameras, MID tablets, optoelectronic technology, and various frequency conversion speed regulation equipment.
