12th October 2009: IQD unveils new miniature quartz crystal oscillator
In response to latest generation electronic designs where size and space is all important, IQD has introduced a new miniature quartz crystal oscillator measuring just 3.2 x 2.5mm in a ceramic package with a hermetically sealed metal lid. The CFPS-39 offers an HCMOS output, operating from a 3.3V supply with both commercial (–10 to +70°C) and industrial (–40 to +85°C) temperature ranges available. Frequencies from 1.8MHz to 50.0MHz can be specified along with stabilities down to ±25ppm… Read More
Tight Tolerance Timing Oscillators
IQD's new CFPS-107/108/109 series watch crystal (32.768kHz) oscillator is unusual in that by using a high internal frequency and achieving its output by division, ‘standard AT' stabilities over temperature of typically 20ppm can be realised rather than the 80ppm or so more usual with existing watch crystal oscillators.
Housed in a miniature 2.6x2.1mm ceramic package, the unit delivers a CMOS output whilst operating from a supply voltage as low as 1.8V; supply voltages of 2.5V and 3.3V can also be specified. Offering a real time clock, the device lends itself to applications predominantly in the consumer and industrial sectors of the electronics industry.
The device is available in both bulk pack and on tape and reel.
Quartz Crystals
IQD offers a very wide range of Quartz Crystals covering the whole range from surface mountable devices through into legacy leaded devices.
IQD is able to offer products to suit a very wide range of applications with many devices suitable for custom applications.
MEMS
Micro Electro Mechanical Systems (MEMS) are a recently introduced product range from IQD.
They offer a low susceptibility to shock and vibration compared to quartz products and are primarily intended for high volume applications such as in automotive applications and consumer requirements.
IQD offers the latest technology in supporting this product range.
VCXOs
Voltage Controlled Crystal Oscillators (VCXO) from IQD offer a wide range of pullabilities and outputs.
They are normally used in conjunction with a phase locked loop.
IQD is able to offer a wide capability and can often look at custom designs for specific applications.
TCVCXOs
Temperature compensated voltage controlled crystal oscillators (TCVCXO) from IQD offer stabilities down to below 1ppm while offering voltage control up to +/-50ppm. They are used where the stability of a simple packaged crystal oscillator (SPXO) is insufficient as well as offering the ability to pull back to nominal frequency where there is a change of circuit conditions. IQD is able to consider custom designs.
Product Applications
CFPS-34 – SMD CLOCK OSCILLATOR
Offering low phase jitter of under 1pS over a bandwidth of 12kHz to 20MHz, the CFPS-34 oscillator is suitable for incorporation into the latest telecommunications infrastructure designs where fast rise and fall times are required for reliable data rate transfer. This surface mount oscillator is housed in an industry standard 7x5mm ceramic package and provides a dual LVPECL output across the frequency range 75.0MHz to 170MHz. The CFPS-34 can be ordered in either bulk or tape and reel packaging.
SPXOs (Clock Oscillators)
Simple packaged Crystal Oscillators (also known as Clock Oscillators) from IQD are available in a very wide range of miniature surface mountable technology as well as leaded, legacy technology.
Covering virtually all applications within the electronics industry IQD is able to offer a custom design and application service to meet every need that you may have.
Programmables
These products offer an ideal solution where customers require a short delivery in order to try out an idea. IQD offers a comprehensive range of programmable oscillators covering both SPXO's and TCXO'S. IQD can offer packages which encompass both 7x5mm and 5x3.2mm packages. IQD can offer programming within a 24 hour period if the requirement is urgent.
TCXOs
Temperature compensated crystal oscillators (TCXO) from IQD offer stabilities down to less than 1ppm.
They are used where the stability of a simple packaged Crystal Oscillator (SPXO) is not sufficient. IQD offers packages down to 5x3mm.
IQD is able to offer custom designs for specific applications.
OCXOs
Oven controlled Crystal Oscillators (OCXO) from IQD offer the ultimate piezo electric performance.
Frequencies up to 60MHz can be provided with a wide range of supply voltages and outputs available.
IQD specializes in offering a customisation service for specific applications.
