Munich, May 3, 2018 – Epson’s CMOS Simple Packaged Crystal Oscillators (SPXO) contain a Quartz crystal and an oscillator integrated circuit.
For dependability, Epson CMOS SPXOs use only fundamental-mode crystals. Compared to PLL-based oscillators, fundamental oscillators dissipate less power and do not generate reference and mixing spurs.
Epson’s fixed-frequency CMOS output SPXOs provide high performance and low power consumption in a variety of industry-standard small surface mount packages and are suitable for all applications.
Epson’s CMOS SPXOs are available in sizes from 7.0 mm x 5.0 mm to 2.0 mm x 1.6 mm, cover temperature ranges up to -40 °C to +105 °C and use an industry-standard pin out.
