Time Base Oscillator: Supply Voltage 1.8V to 5.0V

Component Specifications

Definition

A Time Base Oscillator is a critical electronic component that produces a highly stable and accurate frequency reference signal, typically using quartz crystal or MEMS technology. It serves as the primary timing source for timestamp units in industrial machinery, ensuring precise synchronization of operations, data logging, and event sequencing. This component maintains consistent frequency output despite environmental variations like temperature changes and vibration.

Working Principle

The oscillator operates on the piezoelectric effect (in quartz versions) or micro-electromechanical resonance (in MEMS versions). When voltage is applied, the quartz crystal or MEMS structure vibrates at its natural resonant frequency. This mechanical vibration is converted into an electrical signal through feedback circuits, creating a stable oscillating output. Phase-locked loops (PLL) may be used to multiply or divide the frequency as needed for specific applications.

Materials

Quartz crystal (SiO₂) with silver or gold electrodes, ceramic or metal packaging; or silicon for MEMS oscillators with semiconductor materials.

Frequently Asked Questions

What is the difference between a Time Base Oscillator and a regular clock oscillator?

Time Base Oscillators are specifically designed for precision timing applications with higher stability requirements, typically offering better frequency accuracy, lower phase noise, and superior temperature performance compared to standard clock oscillators.

How does temperature affect oscillator performance?

Temperature variations cause frequency drift in oscillators. High-quality Time Base Oscillators use temperature-compensated (TCXO) or oven-controlled (OCXO) designs to minimize this effect, maintaining stability within specified ppm ranges across operating temperatures.
