New Temperature Robust Precise Quartz Oscillators

Würth Elektronik launches further WE-SPXO series quartz oscillators onto the market. The additions to the program include a new design with LVDS or LVPECL output signal plus 32.768 kHz oscillators.

While the hermetically sealed oscillators were already outstandingly well specified for a wide range of industrial applications, the new arrivals are even more temperature-stable and also more precisely optimized for specific requirements.

The Würth Elektronik oscillators with LVDS or LVPECL output and frequencies from 100 to 156.25 MHz (models IQXO-618-18, IQXO-618-33, IQXO-623 and IQXO-624) are designed for applications with higher data rates: Gigabit Ethernet, Fibre Channel, PCI Express and SONET/SDH.

The WE-SPXO oscillators—now available with differential LVDS or LVPECL output signal—feature improved jitter performance and higher noise immunity of the output signal. Their temperature range of -40 to +105°C also exceeds the normal standards.

Better than watch quartz

With the new 32.768 kHz oscillators (models CFPS-102, CFPS-104, CFPS-107, CFPS-109, IQXO-402, IQXO-404), Würth Elektronik offers electronic developers an alternative to watch quartz crystals.

Available in three package sizes (3.2 × 2.5, 2.5 × 2.0 and 2.0 × 1.6 mm), the oscillators are very robust with a possible temperature range of -40 to +125°C and offer stability up to ±25 ppm.

The big advantage compared to normal watch quartz crystals is their improved frequency stability over the temperature profile and thus also their accuracy. Unlike watch quartz, no additional oscillation circuitry is necessary. This saves design time and reduces the number of components on the PCB. Thanks to their accuracy and reliability, the new oscillators from Würth Elektronik are ideal for real-time clock microcontrollers and for all kinds of electronic devices in which the time of day is important—from laptops, smartphones and consumer electronics to washing machines, ATMs and industrial control systems.

All WE-SPXO quartz oscillator models are now available from stock without a minimum order quantity. Free samples can be requested.
