SPXOs target networking with low jitter performance
Simple packaged crystal oscillators (SPXOs) in the E-Series from Epson Europe Electronics have low jitter. The SPXOs are available with LVPECL or LVDS outputs.
The SPXOs are designed for high-performance networking applications and cover a frequency range of 25 to 200MHz and feature low jitter to deliver wide-open eye diagrams for high-speed (up to 400Gbits per second) optical and electrical interfaces.
The integration of an LDO and the use of Epson’s High Frequency Fundamental (HFF) crystal technology, enables the E-Series SPXOs to reach industry leading jitter levels of 50fs rms jitter at 156.25MHz at low power with a +2.5 or +3.3V supply voltage, claims Epson.
Tight stability (±25 parts per million (ppm) -40 to +85 degree C, ±50 ppm -40 to +105 degrees C, or ±100 ppm -40 to +105 degrees C) provides margin to networking specifications and a wide temperature range supports outdoor equipment and equipment without fans, adds Epson. Two package sizes are available, an industry standard size of 7.0 x 5.0 mm2, and a small version that measures 3.2 x 2.5 mm2 for space constrained designs.
