The IQOV-162 series, a minature OCXO from IQD, delivers a frequency stability down to ±5ppb over the full industrial temperature range from –40 to 85°C. Measuring 4 x 9.0mm, with a height of 6.5mm, the OCXO model is available in a wide frequency range from 10 to 100MHz. 

Specifically designed for LTE & 4G base stations, the IQCM-100 GPS advanced OCXO (Oven Controlled Crystal Oscillator) module has been introduced by IQD Frequency Products. It achieves a holdover specification of 1.5ms over a 24 hour period when locked to a 1PPS (Pulse Per Second) input from an external GPS receiver, easily meeting industry standard holdover requirements.

At embedded world 2014, IQD Frequency Products has released the IQMT-100 series Microcomputer Compensated Crystal Oscillator (MCXO). Offering customers OCXO performance in a standard clock oscillator sized package, this device delivers ±50ppb stability in an industry standard sized ceramic package measuring just 7x5mm.

Launching at Embedded World 2014 in Nuremburg, Germany, February 25-27, the IQXT-200 series is designed specifically to replace an Oven Controlled Crystal Oscillator (OCXO). This Temperature-Compensated Crystal Oscillator (TCXO) is a practical alternative to OCXOs in portable instrumentation equipment and communications systems (fixed and mobile) requiring a high stability oscillator, without the physical space for or power to driv...

Clock references empower modern communications, but making room for even more connections will require new solutions to creating even more stable clock sources. By Uwe Schweickert, R&D Manager at IQD FOQ GmbH.

IQD has launched a new custom crystal filter product platform. The IQXF-1000 series are a range of band-pass filters with centre frequencies from 1.4 to 200MHz based around fundamental and third overtone mode crystals. These 2 to 12 pole crystal filters can operate over a temperature range of –55 to +85 degrees C with a bandwidth @3dB from ±2kHz and with the passband ripple as low as 0.5dB and insertion loss down to 2.5dB.

IQD présentera une nouvelle gamme de filtres à quartz lors de l’exposition European Microwave Week 2013.  L’ IQXF-1000 est une gamme de filtres à bande passante avec des fréquences centrales allant de 1.4 à 200 MHz avec des quartz en mode fondamental et 3ème harmonique. Ces filtres quartz de 2 à 12 pôles opèrent sur des plages de températures de -55 à +85...

Le nouvel OCXO, l’IQOV-200F de IQD offre une optimisation du bruit de phase exceptionnelle allant jusqu'à  -130dBc @ 100HZ et un seuil inférieur à -180dBc sur une plage de hautes fréquences allant de 80 à 130MHz.

IQD have today announced the introduction of the IQOV-200F OCXO, delivering exceptional phase noise performance with a close-in measurement of -130dBc @100Hz and a noise floor better than -180dBc across a high frequency range of 80 to 130MHz. Phase noise is the term used to quantify signal noise in the frequency domain and such phase noise measurements and specification limits are common to most RF engineers in their work.

IQD Frequency Products vient de lancer un des quartz les plus petits au monde, le IQXC-42. Ne mesurant que 2.0 x 1.6 mm et seulement 0.5 m de hauteur, ce nouveau modèle, ultra-miniature, est particulièrement adapté aux applications portables telles que les appareils de gestion de stock, les outils de télémétrie rechargeables, les ordinateurs ultra-portables ainsi que les équipements de surveillance...

IQD Frequency Products has today announced the introduction of one of the world’s smallest quartz crystals, the IQXC-42. Ideally suited for portable applications such as hand held inventory control devices, battery powered telemetry equipment, notebook computers and surveillance devices, the IQXC-42 measures just 2.0 x 1.6mm with a height of only 0.5mm.

IQD today introduce a new series of surface mount oscillators, the HGXO series. Although designed for military applications such as smart munitions and projectile electronics, the HGXO series are also suited for demanding industrial applications. Able to survive shock levels of up to 100,000G, the new oscillators are designed around a hermetically sealed high-shock crystal and a CMOS compatible integrated circuit.

IQD Frequency Products has chosen IMS 2013 to launch a new series of high performance customisable Voltage Controlled Oscillators that provide a comprehensive solution for a diverse range of applications such as test and measurement, SATCOM, Telecom, and digital mobile radio. The new IVCO-100 series offers frequencies from 50MHz up to 6GHz.

IQD’s new IQOV-200 series Oven Controlled Crystal Oscillator has been designed from the ground up to optimise low phase noise performance. Phase noise is caused primarily by semiconductor thermal noise but noisy resistors, capacitors and inductors can all have an effect, as can poor signal transfer paths due to circuit layout and design.

IQD’s new IQXV-40 series Voltage Controlled Crystal Oscillator launching at Design West 2013 satisfies market demand for smaller package styles and low jitter. Measuring just 3.2 x 2.5mm and housed in a hermetically sealed package with a grounded metal lid for low EMI radiation, the new model offers a period jitter of 100ps peak-to-peak maximum.

IQD’s new IQXT-60 series Temperature Compensated Crystal Oscillator offers excellent phase noise performance in a miniature low height package. With typical phase noise figures of -63dBc/Hz at 10Hz and -161dBc/Hz at 100kHz coupled with a low current consumption of around 5.0mA, the new model is a very versatile high performance oscillator.
