The SG-8000 series of programmable high-frequency quartz oscillators entered volume production in 1997. These quartz devices, which were developed in response to users' needs for shorter lead-times, introduced a new and innovative concept: They allowed users to freely select and set the oscillation frequency.

The oscillators in the SG-8000 series could be programmed to produce some 30,000 different frequencies, a number that represented approximately 80% of the standard frequencies used in the market. Equipment makers were thus able to use the same oscillator for a variety of different products simply by selecting a frequency in a program.

The SG-8000 series of quartz oscillators also enabled Epson to dramatically shorten the time it took to ship a product once the order was received. In fact, the lead-time for one of the new oscillators was only one-third that of a conventional oscillator. Even for volume-produced items, the versatility of this series meant that there was no need to keep an inventory of quartz oscillators with different functions and frequencies.
