Programmable crystal oscillator SG-8101/9101 with frequency range of 0.67MHz~170MHz (with frequency spreading function)

With the increasing demand for miniaturized, multifunctional, and highly reliable electronic instruments/products in the market, market changes are constantly updating, and product development cycle time requirements are becoming shorter and shorter. Therefore, engineers' requirements for various components in the product BOM are also constantly changing. Similarly, the demand for crystal oscillators, which serve as multiple product clock sources, also changes rapidly. Often, after a project starts, the frequency point, frequency offset, or other parameters of the crystal oscillator need to be changed several times until the project is completed.

Traditional quartz crystal oscillators have excellent performance, but most of them are made by cutting with necessary circuits. Therefore, their characteristic is that the design and manufacturing cycle of crystal oscillators at different frequencies is relatively long. If an engineer urgently needs special frequency points for the project and uses specially packaged crystal oscillator products for design and testing, it is likely that they cannot obtain samples of the corresponding frequency points from the crystal oscillator manufacturer in the short term, which may delay the design cycle and affect the project delivery schedule. EPSON, as a leading global supplier of crystal oscillator products, has launched programmable crystal oscillators SG-8101 and SG-9101 (with frequency spreading function) covering most commonly used frequency ranges (0.67MHz~170MHz) after in-depth research on customer needs.

The emergence of these two crystal oscillators greatly solves the real-time change requirements of engineers for new product crystal oscillators. SG-8101 and SG-9101 are equipped with a highly stable active crystal oscillator (fundamental frequency), which utilizes PLL technology, along with corresponding tool software and external programmers, to easily adjust the frequency division/doubling parameters and burn them online. In just a few minutes, they can be customized into a brand new crystal oscillator that meets the customer's needs.

In order to meet the needs of more users, especially those who are sensitive to EMI, SG-9101 provides spread frequency function, which can provide center spread frequency and downward spread frequency. The spread frequency depth ranges from ± 0.25% to ± 2.0% (center spread frequency) and -0.5% to -4.0% (downward spread frequency). However, a high spread frequency may exceed the maximum rated frequency of the system or be lower than the average frequency, affecting system stability. It is necessary to choose an appropriate spread frequency percentage according to the requirements. In addition, in order to meet the needs of different users, SG-8101/SG-9101 offers multiple packages including 2520/3225/5032/7050, especially the small package model of 2520, which greatly saves users' PCB area. In addition, the SG-8101/SG-9101 has extremely low power consumption (see table below for details) and can provide high-precision frequency offset indicators up to 15 ppm, far ahead of similar products from other manufacturers. What is even more pleasing is that the SG-9101CGA product has already met the AEC-Q100 standard, and EPSON can also meet the fast sample requirements of automotive grade.
