Coftech Quartz Crystal Products

Coftech is your specialist for quartz crystal products. We provide SMD crystal units, crystal oscillators, crystal filters and customer-oriented advisory services.

Crystal components for the wireless communication market

For more than 30 years, we have built up close and trusting relations with leading companies in the wireless communications market. Coftech’s close cooperation with leading chip manufacturers for wireless applications ensures maximum performance from the crystal components we offer. Our own stock of standard components means that we are generally able to supply standard and alternative components recommended by leading manufacturers at short notice. As a one-stop supplier, we also offer the smallest crystal components worldwide, various crystal system solutions, crystal filters, crystal oscillators, resonators and SAW filters. The company’s strengths are the successful miniaturisation of its SMD crystal products as well as user-specific product developments.

Coftech is not a supplier in traditional sense, but rather a consulting partner for buyers and technicians. Coftech delivers components for telecommunications, the automobile industry and modern medical technology.

Coftech’s flair for next-generation product development helps customers to find solutions for their innovations. The company takes specific customer demands as a challenge to contribute to the development of technology. Coftech provides a complete service, ranging from technical support at the initial project design phase to timely delivery.

Coftech represents in Europe, amongst others: Tokyo Denpa (TEW), Japan, and SAWNICS, Korea. TEW, is a worldwide leading producer of miniaturised crystal components. TEW offers high-quality innovations and future-oriented solutions. SAWNICS is specialised in high-quality and flexible (e.g. customised solutions) SAW-components.

Quartz crystal units

The TAS 1210 is the smallest crystal in the world, measuring only 1.2mm x 1.0mm x 0.35mm. It has a frequency range of 34MHz to 60MHz.

This ultra miniature SMD crystal unit, due to its low profile and frequency range, is most suitable in small, next-generation mobile devices for modules for M2M, any NFC applications, wireless medical use, mobile phone and tablet PCs.

Temperature compensated crystal oscillator (TCXO)

TTS30VS/NS is the smallest VCTCXO/TCXO in the world, measuring only 2.0mm x 1.6mm x 0.6mm. It is suitable for GPS applications and shows excellent phase noise performance.

This oscillator can be supplied with an enable/disable function for the reduction of the electricity and a maximum supply voltage of 1.68V. In addition, temperature sensor output is available.

TCXOs for MP base station and Femtocell applications

A TCXO with stability of +/-0.05 ppm ( 0°C to +50°C) has recently been developed. It can replace expensive OCXOs.

For GPS/WLAN applications, Coftech provides TCXOs with a package size of 2.5mm x 2.0mm and 2.0mm x 1.6mm with a stability maximum of ±0.5ppm, also available with enable / disable function.

Low EMI clock oscillators

The principle sources of the EMI problem come from the system clocks. Therefore, rather than using ferrite beads, EMI filters and metal shielding, the most efficient and economic way to reduce the peak radiation energy is to use the spread spectrum low EMI clock oscillator.

Package sizes are 7.0mmx5.0mmx1.8mm and 5.0mm x 3.2mm x 1.2mm at a frequency range of 3.5MHz to 220.0MHz.

The low EMI clock oscillators are used in medical telemetry, handheld ID readers, automotive equipment and embedded systems, to name just a few applications.
