Clock Oscillators SPXO

Simple Packaged Crystal Oscillators

IQD’s clock oscillators, also known as simple packaged crystal oscillators (SPXOs), combine a quartz crystal resonator and oscillator circuit in one package. They provide a ready-to-use clock signal for electronic designs, without requiring a separate crystal and oscillator circuit.

Clock oscillators are used in applications including telecommunications, wireless communications, industrial electronics, consumer devices, Ethernet, IoT, wearables, optical networks, audio and multimedia equipment, and test and measurement systems.

IQD offers a broad SPXO portfolio, with frequency, package, output and environmental options that vary by model. Use the product catalogue and individual datasheets to identify a part that meets your design requirements.  App Note | Specifying SPXO

Low Phase Noise Oscillators - For optimum signal quality and accuracy

Phase noise can be defined as the short term, random fluctuations in the oscillator’s frequency domain. For some applications maximum clarity and low phase noise is critical. Such applications include: Wireless communications, radar systems, test & measurement, high‑speed data communications such as DAB, fibre-optic networks, and GNSS receivers, including GPS, GLONASS, Galileo and BeiDou systems. In fact, any application that demands precise frequency control, high signal quality, and low interference can benefit from the use of low phase noise oscillators.  Find out more here...
