Clock Oscillators


A crystal clock oscillator (sometime referred to as a 'standard packaged crystal oscillator or SPXO) is a 'plug and play' quartz crystal. It combines a quartz crystal resonator with an oscillator circuit in a single package to provide a fully functioning stand-alone oscillator circuit. They are used in many telecom, military, industrial and consumer applications. IQD’s comprehensive range of crystal clock oscillators are available in a range of voltages down to 1.8V and in a variety of package sizes including both miniature surface mount (SMD) and thru-hole packages. Our low power oscillators are particularly suitable for use in handheld battery operated products. We also offer low jitter and low phase noise models and many alternative outputs including CMOS, HCMOS, ACMOS, LVPECL, LVDS and TTL. In addition, our range of factory programmable oscillators allow for very short lead times down to 3 days for custom frequencies and are available in a variety of packages sizes and specifications.

IQD's range of automotive clock oscillators are suitable for most automotive applications and are available to AEC-Q200 and TS16949 are available with PPAP levels 1 to 5. Typical applications for IQD's automotive oscillators include ABS and Airbag sensors, Engine Control Units (ECU), High speed automotive networks and Tyre Pressure Monitoring System (TPMS) receivers.

As a previous division of Rakon, IQD maintains a close partnership as a worldwide channel partner supplying Rakon’s  wide range of high performance and high reliability Crystal Oscillators(XOs). The high performance range of XOs feature low jitter, low phase noise, and selectable output frequency options; these features make them ideal for applications in Global Positioning and Telecommunications markets. The high reliability XO ranges are resistant to shock and vibration in harsh environments and the specification profile makes it a great solution for Space and Defence applications.

Our technical information pages includes a range of application notes for clock oscillators including 'Frequency Control for Telecommunications', 'Jitter and Phase Noise' and 'Pluto™ Temperature Compensation'.
