Epson Toyocom Announces New Programmable Crystal Oscillators to Support Low Voltage & High Frequencies


Epson Toyocom Corporation, a leader in the design and manufacture of crystal-based electronic products, today announced the commercial development of a new series of programmable crystal oscillators*1 [simple packaged crystal oscillator (SPXO)] for use as clocks in office equipment, PCs, mobile devices and other general consumer electronics. The new SG-8003CE series oscillators will be the first programmable SPXOs to support low voltages and high frequencies. Volume production will begin in January 2008.

The new SG-8003CE series, which supports voltages down to 1.8V and 2.5V and frequencies up to 166 MHz, fills the low-voltage, high-frequency needs that Epson Toyocom’s highly popular SG-8002 series of programmable crystal oscillators, released in 1997, could not. Moreover, the new programmable crystal oscillators not only support low voltages, they consume 50% less current than their predecessors, making them an excellent choice for a wide range of mobile devices and other equipment where low power consumption is critical.

With a package measuring just 3.2 x 2.5 mm, the SG-8003CE series also answer market needs for a smaller form factor. Epson Toyocom, committed to further package downsizing, intends to employ its QMEMS*2 technology to expand its lineup of miniature crystal device products, especially by rolling out the 2.0 x 1.6 mm NPO*3 structure already developed for SPXOs and TCXOs (temperature-compensated crystal oscillators).

SG-8000CE series and other crystal devices will be on display at the Epson Toyocom booth (No. 6E116) at CEATEC JAPAN 2007, to be held at Makuhari Messe from October 2 to 6.


* Low-voltage support (1.8V, 2.5V, 3.3V)
* Low current consumption (7 mA Typ., 50% lower than previous programmable SPXOs) Note: At 125 MHz, Vcc 3.6V, no load condition
* Jitter (up to 250 ps) Note: Period jitter, 27 MHz or higher
* High-frequency support (from 1 MHz up to 166 MHz)
