IQD, a Würth Elektronik eiSos Group company, introduces crystal oscillators for demanding applications. The IQXT-601 and IQXT-602 are clipped-sine TCXOs available over a frequency range of 10 MHz to 55 MHz. Some frequencies have been specifically selected to meet the reference requirements of global navigation satellite systems and RF-sensitive timing applications. This means that engineers working on GNSS receivers, positioning systems, or RF front ends no longer have to compromise on frequency selection, helping to reduce time to market.

The new TCXOs are housed in SMT-mountable ceramic packages measuring just 2.0 × 1.6 mm or 2.5 × 2.0 mm and feature a clipped-sine output. This makes them a compact, high-performance timing solution for positioning, wireless, and RF applications that require particularly space-saving, miniaturized electronics.

Both components offer frequency stability of ±0.5 ppm across the entire industrial temperature range of -40 to +85°C, along with good low phase noise performance. So they offer a clean, stable reference for demanding timing architectures. The TCXOs operate at supply voltages from 1.71 V to 3.63 V, allowing them to be used with both 1.8 V and 3.3 V rails. This allows greater flexibility when integrating the oscillators.

The basis for accurate clocks

The clipped-sine TCXOs provide precise, temperature-compensated frequency control for a wide range of applications, including GNSS and RF-sensitive timing applications for navigation and telematics, wireless networks, smartphones and wearables, low-power wide-area network and IoT modules, as well as other RF-sensitive applications.
