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.
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.
Saw Filters
IF & RF Surface Acoustic Wave (SAW) Filters are used in a wide range of electronic applications where control of the output and input signal is crucial. IQD’s comprehensive range of IF & RF SAW Filters are available in a variety of package sizes...
Crystal Filters
Discrete & Monolithic Crystal Filters (MCFs) use quartz as the prime filtering element. The crystal's high Q factor and tight stability ensure that the filter topology has a precise centre frequency and a sharp pass-band response.
VCOs & Synthesisers
IQD’s range of Voltage Controlled Oscillators (VCOs) are ideal for applications such as SATCOM, digital radio, WiMax, RF repeaters, test & measurement synthesisers, cable infrastructure, radar, telecom and telemetry.

Featured Product
IQD’s high performance oscillator, IQRB-1, offers a stability around a 1,000 times more accurate than a typical Oven Controlled Crystal Oscillator (OCXO). This Sub Miniature Atomic Clock (SMAC) is housed in a 5-pin 51mm square package making it compatible with many existing OCXO footprints whilst offering considerably improved performance. Operating at a standard frequency of 10MHz, the IQRB-1 can accept supply voltages of between 12 and 18 Volts. Applications include LTE (Long Term Evolution) systems that require exceptional timing accuracy. It can also be used for UTMS as well as extended holdover for CDMA and WiMax.
‘Circuit Characterisation’ Service
This service ensures that the correct crystal specification and associated oscillator circuit is used to enable the chipset to work correctly within the application. By doing so it eliminates issues that can occur which include start-up problems with the quartz crystal.
