The Epson SG-8201CJA programmable oscillator has amazing frequency control capabilities. Its output frequency range is from 1.2MHz to 170MHz, which almost covers various common frequency requirements in modern electronic devices. It can accurately adapt to both low-frequency sensor signal processing and high-frequency high-speed communication modules. Moreover, it can still maintain high frequency stability under different temperature environments. For example, within a wide temperature range of -40 ° C to+105 ° C, the frequency tolerance can reach ± 15 × 10 ⁻⁶, and even in the more extreme temperature range of -40 ° C to+125 ° C, the frequency tolerance can be controlled within ± 25 × 10 ⁻⁶ or ± 50 × 10 ⁻⁶. This precise frequency output is like injecting a stable "heart" into the electronic system, ensuring that every operation can be carried out at an accurate time rhythm.

This programmability is like a master key, opening the door to meet various special frequency requirements. Whether it is developing new electronic products or upgrading existing equipment, it can greatly shorten the development cycle and reduce costs. No longer need to worry about finding a standard oscillator for a specific frequency, nor do you need to make complex circuit adjustments, everything becomes simple and efficient.

（四） Advanced phase-locked loop technology

SG-8201CJA adopts advanced low-noise fractional N-phase-locked loop technology internally. This technology is not only key to achieving precise frequency control and adjustment, but also endows it with the ability to support output frequencies up to 170MHz. Through phase-locked loop technology, oscillators can maintain stable performance in complex working environments while providing reliable support for applications that require high frequencies, like a skilled conductor who precisely regulates the "movement" of the entire electronic system behind the scenes.

（五） Excellent temperature compensation function

In practical applications, electronic devices may face various harsh temperature environments. But SG-8201CJA can handle it calmly, thanks to its excellent temperature compensation function. Whether in high-temperature industrial environments or low-temperature outdoor conditions, it can consistently maintain stable frequency output. This stability under temperature changes makes it excellent in temperature sensitive fields such as automotive electronics and industrial control, making it a reliable clock signal source.

（六） Compact packaging design

Epson is well aware of the pursuit of miniaturization and integration in modern electronic devices, so the SG-8201CJA adopts a small package size of 2.0 × 1.6mm. This compact design is like a small sprite that can easily integrate into various limited space circuit boards, providing an ideal solution for the miniaturization design of electronic devices. In consumer electronic devices such as smartphones, tablets, and various high-density circuit board applications, it saves valuable space without sacrificing performance, providing electronic engineers with more design freedom.
