Crystal oscillators have architecture choices

Epson Europe’s industry-standard, fixed-frequency, differential output simple packaged crystal oscillators (SPXO) are now available in three architectures: AT, AT HFF and AT+PLL.

The cost-optimised differential SPXOs have power consumption as low as 25mA maximum in a variety of industry-standard, small, surface mount packages to match any application, claims Epson.

Epson uses traditional AT-cut crystals and PLLs and also high frequency fundamental (HFF) crystals. All Epson’s timing products use only fundamental-mode crystals for superior reliability.

Epson’s differential output SPXOs are available in sizes from 3.2 x 2.5mm to 7.0 x 5.0mm, and cover temperature ranges from -40 to +105 degree C, and use an industry-standard pin out with LV-PECL, LVDS, and HCSL output options.

Stability is ±20 parts per million (ppm), ±25, ±30, ±50 and ±100ppm. Supply voltage ranges from 2.5 and 3.3V (2.375 to 3.6V).

Epson’s product portfolio ranges from inkjet printers and digital printing systems to 3LCD projectors, watches and industrial robots.  Led by the Japan-based Seiko Epson Corporation, the Epson Group comprises more than 76,000 employees in 87 companies around the world.
