Seiko Epson has expanded its portfolio of programmable crystal oscillators with the SG-8101 series and SG-9101 series. Drawing 2.9mA to 7mA over the 20MHz to 170MHz range (with a 3.3V supply voltage), the devices feature a 50 per cent lower current consumption than comparable Epson products.

The SG-8101 also has 66 per cent tighter frequency tolerance (±15 ppm in the -40°C to 85°C temperature range). Users will be able to programme both the SG-8101 series and the spread-spectrum oscillators that reduce spectral EMI emissions in the SG-9101 series with an SG-Writer II programming tool.

Volume production is scheduled to begin in June 2016. In addition to a 2.5mm x 2mm package that will enable electronics manufacturers to save board space, the oscillators will also be available in popular package sizes including 3.2mm x 2.5mm, 5mm x 3.2mm and 7mm x 5mm.
