Programmable SPXOs support low voltages, high frequencies

Epson Toyocom Corp. has announced the commercial development of a new series of programmable simple packaged crystal oscillators (SPXOs) 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, the company claimed. 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 166MHz, fills the low-voltage, high-frequency needs that Epson Toyocom's 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 percent less current than their predecessors, the company said, making them a suitable choice for a wide range of mobile devices and other equipment where low power consumption is critical.

With a package measuring just 3.2mm x 2.5mm, the SG-8003CE series also answer market needs for a smaller form factor. Epson Toyocom intends to employing its QMEMS technology to expand its line of miniature crystal device products, particularly by rolling out the 2mm x 1.6mm NPO structure already developed for SPXOs and TCXOs.
