Description
Epson’s SG-8018 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
SG-8002/SG-8003 series, 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. The oscillator in the SG-8018 series have an approximately 66 % tighter frequency tolerance and
50 % lower current consumption than comparable products, and can be used under a wide range of
environmental conditions. This will also significantly contribute to performance, lower power requirements, fast
development cycles, and low-volume production.
