Product Ranges
Quartz Crystals
Quartz crystals are used in a wide range of electronic applications. The High Q factor of the quartz means that tight stabilities can be achieved; this is key to ensuring microprocessor timing circuits work correctly within customer’s designs. IQD offers an extensive range of Quartz Crystals covering both surface mount and legacy leaded devices that satisfy most applications; many devices are suitable for custom designs.
Crystal Clock Oscillators
Crystal Clock Oscillators are a “plug and play” quartz crystal and 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 sizes including both miniature surface mount (SMD) and leaded packages. Our low power versions are particularly suitable for use in handheld battery operated products. We also offer low jitter/phase noise options and many alternative outputs such as LVPECL, LVDS, TTL, and Spread Spectrum.
MEMS Oscillators
IQD’s Micro Electro Mechanical Systems (MEMS) oscillators are a silicon based alternative to traditional quartz based oscillators. They offer low susceptibility to shock and vibration compared to quartz based products and are primarily intended for high volume applications in automotive and consumer markets. Our range of MEMS Oscillators includes both standard Clock and Voltage Controlled versions (VCMOs). One of the big advantages of MEMS oscillators is their very short production lead-times; they also offer a viable alternative to programmable crystal oscillators in some applications.
Fast Make Programmable Oscillators
Programmable Oscillators are PLL based and are one time programmable by IQD. They provide an ideal solution where customers require a short delivery for prototyping or urgent production runs. IQD offers a comprehensive range of programmable oscillators covering both SPXO’s and TCXO’S. Our range includes 7x5mm, 5x3.2mm, 3.2x2.5 and 2.5x2.0 package sizes and we offer programming within a 24 hour period for urgent requirements.
Automotive Crystals & Oscillators
IQD’s comprehensive range of Automotive Crystals and Oscillators are qualified to AEC-Q200 standard and can be released to TS16949 where required. Full PPAP documentation (levels 1 to 5) is also available if requested. All types of automotive applications are covered by IQD’s range including safety critical applications such as braking systems, engine management systems and anti-skid control as well as more standard requirements such as instrumentation and entertainment systems. Standard operating temperature ranges are –40 to +85°C and –40 to +125°C. Our package styles tend to follow those of mainstream products but with enhanced performance capabilities.
VCXOs
Voltage Controlled Crystal Oscillators (VCXOs) are used mainly in the telecom, test and broadcast industry. They enable customers to adjust the frequency by as much as ±150ppm while the circuit is active and so match an incoming signal. IQD’s VCXO’s are available with a wide range of pullabilities and outputs; they are normally used in conjunction with a phase locked loop. We offer a wide capability and can consider custom designs for specific applications.
TCXOs & TCVCXOs
Temperature Compensated Crystal Oscillators (TCXOs) and Temperature Compensated Voltage Controlled Crystal Oscillators (TCVCXOs) offer stabilities as tight as parts per billion (ppb). They are used where the stability of a standard Crystal Clock Oscillator is insufficient, as well as offering the ability to pull back to nominal frequency where there is a change of circuit conditions. A TCVCXO offers the voltage control function to allow precise tuning of the output frequency after PCB assembly and later, to compensate for any effects of aging. Our standard range covers virtually all applications within the electronics industry with package sizes down to 2.5x2.0mm. We also offer a Custom Design and Application Service to meet specific customer requirements.
OCXOs
Oven Controlled Crystal Oscillators (OCXOs) deliver the ultimate piezo electric performance with stabilities down to less than ±1ppb. IQD’s range includes frequencies up to 100MHz with a wide choice of package sizes, supply voltages and outputs available. We specialise in offering a customisation service to suit specific applications.
