Description
Epson’s SG-9101 series are Programmable Crystal Oscillator series with CMOS output.
While this series offer the same easy programmability of frequencies and other parameters as comparable earlier
Epson products, they also have a wider operating temperature range, with a top-end limit of 105 °C. In addition to
a 2.5 × 2.0 mm package that will enable electronics manufacturers to save board space, the oscillators will also
be available in the following popular package sizes: 3.2 × 2.5 mm, 5.0 × 3.2 mm and 7.0 × 5.0 mm.
Users will be able to program the products to the required output frequency, as well as to the required spread
spectrum settings, with an Epson SG-Writer II (sold separately).
This will also significantly contribute to performance, lower power requirements, fast development cycles, and
low-volume production.
