YSO212PU Series — Ultra-Low Jitter Programmable Differential Oscillator

The YSO212PU series programmable differential oscillators offer a stable and reliable clock source for demanding applications such as AI computing clusters, cloud computing infrastructure, optical communication transmission equipment, hyperscale data centers, 5G base stations, high-speed Ethernet, and precision test instruments, thanks to their superior low jitter performance, full-band customizable frequency capabilities, and miniaturized and highly reliable design.

Three essential things to know about active crystal oscillators: circuit diagram, pin diagram, and wiring diagram.

The typical usage of an active crystal oscillator is as follows: pin 1 is left floating, pin 2 is grounded, pin 3 is connected to the output, and pin 4 is connected to the voltage.

Crystal oscillator drive power testing and calculation

Test Method： Equipment Preparation: PCB board, crystal oscillator (with equivalent circuit constant data), oscilloscope, current probe. Circuit Connection: Desolder one side of the crystal oscillator pins, connect a lead in series with the current probe, and resolder it back onto the PCB, ensuring the circuit is intact.

The difference between a programmable oscillator and an active crystal oscillator

Active crystal oscillator: A complete module integrating a quartz crystal and oscillation circuit. It directly outputs a square wave signal of a fixed frequency after power-on, requiring no external circuitry. Programmable crystal oscillator: A crystal oscillator whose output frequency can be set via programming. Users can adjust parameters such as frequency according to their needs, offering greater flexibility.
