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...

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...

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.

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...

OCXOs

Oven Controlled Crystal Oscillators offer frequency stabilities even tighter than those offered by a TCXO. The frequency drift of the quartz crystal due to temperature shift is reduced by heating the crystal in an oven and so holding the temperature of the quartz at a fixed point.

Advanced Modules

Frequency control products incorporating more than just an oscillator. IQD can develop sophisticated modules to incorporate the horizontal integration of the functions required by our frequency control product users.

Rubidium Oscillators

The Sub Miniature Atomic Clock (SMAC) is housed in a 5 pin 51mm square package making it compatible with many existing OCXO footprints whilst offering considerable improved performance.

Real Time Clocks

A Real Time Clock (RTC) is an integrated circuit which keeps very accurate track of time and is used in a wide range of electronic equipment where time, day, month, year and an alarm function is required. IQDs range of RTC includes a 32.768kHz crystal and a digital compensated TCXO.
