Share | Several knowledge points about programmable crystal oscillator chips [Copy link]

What is a programmable crystal oscillator? Programmable crystal oscillators are mostly active crystal oscillators, which are composed of two chips; one is an all-silicon MEMS resonator, and the other is a chip with temperature compensation function, which can start the circuit phase-locked loop CMOS. It uses standardized semiconductor chip MCM packaging. It can use fully automatic standard semiconductor manufacturing processes, such as ICs used in current electronic product design, with good stability and quality; human errors cannot occur during the production process.

In fact, the programmable crystal oscillator has a nice name: silicon crystal

Generally speaking, a programmable crystal oscillator is to provide your crystal oscillator parameters, such as frequency deviation, operating voltage, load capacitance, frequency, etc. to the crystal oscillator manufacturer. The manufacturer can program it through a computer or other equipment and write these parameters into a blank chip by pressing the OK button.

Normally, the production lead time is 1-3 days. We know that for conventional passive crystal oscillators or active crystal oscillators, the production lead time is 2-3 weeks when the wafer is in stock, 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 have advantages not only in terms of lead time, but also in terms of frequency. In terms of function, the problem of temperature drift is completely eliminated.

Fully automatic semiconductor technology (chip level), no airtightness problems, no vibration! Integrated temperature compensation circuit, no temperature drift in the full temperature range, -40~85 full temperature guarantee; mean time between failures (MTBF) up to 500 million hours! Low jitter, low power consumption, high temperature resistance, high pressure, high humidity, good shock resistance.

Support any frequency point from 1-800MHZ, accurately output to 5 decimal places. For example: 65.53500MHz). Support 1.8V, 2.5V, 2.8V, 3.3V multiple working voltage matching! Support 10PPM, 20PPM, 25PPM, 30PPM, 50PPM and other precision matching! International standard QFN package 33607050, 5032, 3225, 2520 programmable crystal oscillator is suitable for clocks, digital products, car digital, mobile phones, walkie-talkies, digital cameras, MID tablet computers, optoelectronic technology and various frequency conversion speed regulation equipment and other communication equipment.
