21st May 2009: Latest Generation of Surface Mount Watch Crystals Introduced
IQD has launched its latest generation of surface mountable watch crystals, the CFPX-217 series which has replaced the CFPX-206. The CFPX-217 operates at a fundamental frequency of 32.768kHz and is housed in an industry standard ceramic package with metal lid and measuring just 3.2 x 1.5 x 0.9mm. With a standard frequency tolerance of ±20ppm and driving a 12.5pF load the CFPX-217 series is operable over a temperature range of -40 to +85˚C, with a frequency stability coefficient of… Read More
CFPS-9 – SMD CLOCK OSCILLATOR
The CFPS-9 HCMOS output clock crystal oscillator is housed in the increasingly popular 5x3.2mm ceramic package. Operating at 3.3V the CFPS-9 is a suitable alternative to the very widely used CFPS-73 series where physical size has become an issue on design up-grades. Both commercial (-10 to +70°C) and industrial (-40 to +85°C) temperature range versions are available. Frequency/temperature stabilities down to ±25ppm can be specified, across the frequency range of 1.8MHz to 160.0MHz. Typically the CFPS-9 can be used in Avionics, Telecoms, RF Systems and computing applications. Packaging can be either bulk or tape and reel.
Crystals for where space is at a premium
For commercial applications such as set-top boxes and card readers where space is at a premium, IQD's new CFPX-181 series of 4 pad crystals provide an ideal solution.
Measuring a miniscule 2.5x2.1mm, the new range is available at fundamental frequencies from 16.0MHz to 50MHz. Frequency stabilities down to 10ppm over an operating temperature range of -10 to +60C may be specified.
The device is available in both bulk pack and on tape and reel.
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.
Product Applications
CFPX-188 – SMD QUARTZ CRYSTAL
Reflecting the trend for ever increasing miniaturisation the CFPX-188 quartz crystal is housed in a 2x1.6x0.45mm ceramic package. The 4-pad device is available in frequencies between 20.0MHz and 50.0MHz with stabilities down to ±10ppm. The standard operating temperature range is -10 to +60°C but wider temperature ranges can be manufactured upon request. The CFPX-188 is suitable for a wide variety of applications including Avionics, Telecoms, Wireless and Metering. The CFPX-188 can be ordered in either bulk or tape and reel packaging.
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.
