We also employ full AS9100 quality assurance certification, ensuring that all our product meet the exacting standards that our customers deserve.

If you have any questions or you'd just like more information on our company, feel free to get in touch. It's also worth noting that our engineering team are on hand to provide advice and assistance, if required.



Quartz Crystals - Visit our website

We manufacture a comprehensive range of quartz crystals and maintain stock of crystals in most popular package styles, specifications and frequencies for fast delivery. If we do not stock the crystal you require, we can provide bespoke crystals to specification in as little as three working days.

This is a brief list of some of the crystals we stock:

• Low-profile, miniature, micro-miniature, ultra-miniature and compact SMD crystals
• Industry standard and miniature cylindrical watch crystals • Ruggedised ceramic
• Miniature leaded crystals with tuning fork resonators for Pierce or series oscillators
• Compact size metal can crystals with very close tolerances available for telecom applications
• High-temperature operating range crystals • High shock and vibration survival crystals


Oscillators - Visit our website

We manufacture oscillators in a comprehensive range of packages and output types, including PECL, HCMOS and LVDS. We make oscillators for a diverse range of applications, from low-cost clock oscillators to high-reliability units for aerospace and defence applications. We offer short delivery lead times, even for production quantities with our XpressO configurable oscillator range.

A wide supply voltage range of from 1.0 to 5.0 Volts can be specified for many HCMOS output SMD oscillators.

We have recently introduced the EQXO75000 series of military specification 7x5mm ceramic packaged clock oscillators manufactured in our new class7 cleanrooms.

We also offer low EMI oscillators which use spread-spectrum technology and can reduce EMI by
- 12dB, making these oscillators a true 'EMI solution in one package'.


Resonators - Visit our website

We offer a wide range of resonators, including ZTTC - SMD resonators with and without capacitors in frequencies ranging from 2.0 MHz to 50.0 MHz. We also offer ZTT resonators, including ceramic resonators with built-in phase-shift capacitors, and ceramic resonators for FM and general applications. These resonators feature stability tolerance of ±0.3%. A comprehensive selection of frequency ranges is available.


Filters - Visit our website

We produce a full range of standard filters and also offer custom filters to specification, including ceramic, helical, microwave and monolithic crystal filters.

Ceramic filters include discriminators and traps with frequency range from 4.5 MHz to 6.5 MHz. Ceramic filters are available in 4 element or 6 elements.

Our helical filters feature low insertion loss and impedance and small group/phase delay. They can be manufactured to any Fo between 55 MHz to 1600 MHz with a customer-specified centre frequency and bandwidth with no NRE design charges.

Monolithic Crystal filters are available in a range of standard specifications for general and other applications including UHF mobile radio, cellular and cordless telephone.

We offer microwave filters to specification.


VCXO - Visit our website

Our extensive range of VCXOs are available in a wide variety of packages with CMOS, LVDS, PECL or Sine Wave outputs.

Among the features and specifications are:

• Square wave CMOS TTL Output in 8 or 14 pin DIL and SMD VCXO • LVDS SMD and Through Hole VCXO
• PECL SMD and Through Hole VCXO • Sine Wave Output 14 pin DIL and SMD VCXO
• Configurable, high-quality XpressO SMD very low jitter VCXOs with production quantity delivery at low cost within two weeks
Our VCSO ranges feature an extensive choice of configurations, frequency and pull ranges.


TCXO - Visit our website

Oven Controlled Crystal Oscillators (OCXO) provide very high degrees of stability in quartz crystal-controlled oscillators. Any variation of output frequency caused by ambient temperature change is minimised by placement of the crystal inside a thermostatically controlled oven.

Our OCXOs are precision designed to provide stabilities from ±0.005ppm over their operating temperature range using SC-Cut crystals or from ±0.02ppm with AT-Cut crystals. Most may be specified with either 5.0 or 12.0 Volts supplies.

We offer a full range of Sine Wave Output OXCOs and Square Wave Output OCXOs in various packaging configurations and specifications, most with EFC voltage control as standard.

SMD TCXO - T1220 - Visit our website

Greenray Industries Inc has surpassed industry standards to create the SMD TCXO - T1220. The device is applicable in the most demanding environments, is fully portable as well as airborne, and benefits from tight stability, low input power (virtually no heat dissipation) and no warm up time. Making it applicable to nearly any process where temperature stabilities more commonly associated with oven controlled temperature compensated (OCXO) devices are required. The devices are a rugged build and very compact, with the industry-standard surface mount package measuring just 20.3 x 12.7 x 8.4mm. These devices come in frequencies between 10 to 50MHz and with either a 3.5 or 5V supply.

Timing Modules - Visit our website

Euroquartz is specialist manufacturer of timing modules. We offer two varieties:

CMOS Timing Modules. 3.3 Volt Supply. 8.kHz to 64kHz inputs (or custom). 20mm leadframe – 14 pin package.
LVPECL Timing Modules. 3. 3 Volt Supply. 8kHz inputs (or custom).

Downloadable data sheets can be found online at www.euroquartz.co.uk.


XpressO Range - Visit our website

As a frequency control specialist we are able to offer a new range of configurable surface mount oscillators that are available on a two week leadtime for production quantities. The Xpress0 range has been configured for any application requiring an oscillator including SONET, Ethernet, storage area networks, broadband access, microprocessors/DSP/FPGA, test and measurement, industrial controllers and fibre channel. The typical specification of 1ps phase jitter, is around ten times better than programmable parts, while the start up time of 10ms and operating temperature range from -40 to +85°C, make these high performance frequency control devices a very attractive package. Full specifications are available on our website and by contacting our team.
