What is the programmable crystal oscillator SG-8101 and SG-9101 series products launched by Epson? A programmable oscillator is a frequency burning oscillator based on PLL technology, which is a single CMOS frequency output. Epson programmable crystal oscillators can replace fixed frequency crystal SPXO oscillators, with faster lead times than fixed frequency oscillators.

Programmable crystal oscillator can be simply understood as providing the required crystal oscillator frequency, voltage, accuracy, load, and other requirements. Through a simple computer editor, you can input these parameters on the computer controller, enter the parameters you provide, and then press the OK button to write the frequency, voltage, and other parameters to the blank crystal oscillator chip.

In today's rapidly developing electronic technology field, precise clock signals are like the beating of a heart, providing crucial power for the stable operation of various electronic devices. As a leader in the industry, Epson has launched the SG-8101 and SG-9101 series of programmable crystal oscillators, which have become an ideal choice for many electronic device manufacturers due to their excellent performance and unique usage characteristics.

The SG-8101 series exhibits astonishing high-precision characteristics. Its standard SPXO accuracy is as high as ± 50ppm (including aging), and the frequency adjustment accuracy can reach 1ppm. This means that whether in complex data processing systems or precision instruments that require extremely high clock accuracy, SG-8101 can ensure the provision of accurate and error free clock signals, safeguarding the stable operation of equipment and the accurate transmission of data.

The wide temperature range is also a major highlight of SG-8101. The wide temperature range from minus 40 ℃ to above 105 ℃ enables it to easily cope with various harsh working environments. Whether in extremely cold polar environments or hot workshops, SG-8101 can always maintain stable frequency output, ensuring the normal operation of the equipment and providing great reliability for your application scenarios.

The low power consumption characteristics make SG-8101 outstanding in terms of energy conservation and environmental protection. The power supply voltage ranges from 1.62V to 3.63V. When the output frequency is 20MHz, the no-load current loss is as low as 2.7mA, and the static current in standby mode is only 0.3 μ A. For battery powered devices, this is undoubtedly a blessing in extending battery life and making an important contribution to reducing overall energy consumption of the equipment.

Quick start is another advantage of SG-8101. With a startup time of only 3ms and a rise/fall time of only 3.0ns in default and fast modes, the device can quickly enter a stable working state, greatly improving the system's response speed, reducing waiting time, and bringing a qualitative leap to your work efficiency.

Strong programmability is one of the core competencies of SG-8101. Through programming tools such as SG Writer II, users can flexibly set parameters such as output frequency, rising edge, and falling edge time. Whether it's rapid prototyping applications, alternative interactive periodic on-site product solutions, or meeting the needs of non-standard frequency applications, SG-8101 can easily handle them, bringing unprecedented flexibility to system design.

The SG-9101 series stands out with its unique spread frequency function. This series of products can reduce EMI (electromagnetic interference) by adjusting the clock frequency, providing multiple modulation methods such as modulation with Sa values of ± 0.5%, ± 0.75%, ± 1%, ± 1.5%, ± 2%, and 0.25%, and introducing minimal clock signal jitter. This feature effectively reduces electromagnetic radiation power and minimizes the impact of EMI electromagnetic interference, providing a perfect solution to the problem of EMC radiation exceeding standards.

The parameter programmable range of SG-9101 is extremely wide, with a frequency programmable range of 0.67MHz to 170MHz (1ppm per step) and an extended frequency range of ± 0.25% to ± 4%. Users can use the SG Writer II dedicated burner to define parameters such as center frequency, meeting specific frequency requirements for different application scenarios and providing a more flexible clock solution for electronic devices.

The wide range of application areas is also a major advantage of SG-9101. Its working temperature range is wide, with an upper limit of 105 ℃, and it provides a variety of common packaging sizes, which can be widely used in communication devices such as car digital devices, clocks, digital products, mobile phones, walkie talkies, digital cameras, tablets, optoelectronic technology, and various frequency control devices to meet the application needs of different fields.

Epson's programmable crystal oscillators SG-8101 and SG-9101 series products provide excellent clock solutions for electronic device manufacturers due to their unique features such as high precision, wide temperature range, low power consumption, fast start-up, strong programmability, and frequency spreading function. Choosing Epson means choosing quality and reliability. Let's work together to lead the new trend of clock precision in the field of electronic technology.
