Programmable OscillatorsProgrammable oscillators or voltage-controlled crystal oscillators, or VCXOs, are a type of oscillator and timing device employed in numerous, diverse applications spanning industries as wide-ranging as aerospace, industrial automation, military and consumer electronics. SIT1602ACE7-25S is an example of a programmable oscillator; its features, application field and working principle will be discussed in greater detail in the following sections.Technical SpecificationsThe SIT1602ACE7-25S programmable oscillator is a 19.44MHz device, with a frequency stability of ±50 ppm. It includes SMD (Surface Mount) phase-locked loop (PLL) technology and has a 1.8 V @ 25 mA typical supply current. It is packaged in an 8x2mm, 4-pad ceramic package module, with a supply voltage range of 1.6V to 3.3V. Working Principle Programmable oscillators, such as the SIT1602ACE7-25S, depend on PLL-compatible oscillators that are tuned to a specific frequency. These crystal oscillators have a low-noise core (quartz crystal) whose characteristics are kept tightly regulated. The PLL works by comparing the input signal frequency to the reference signal, and then using a gain element to amplify the difference between the two signal frequencies. The amplified signal is then used as the control voltage for the oscillator, allowing for precise tuning and adjustment of the frequency.Application FieldThe versatility of programmable oscillators makes them suitable for numerous applications in various industries including military, aerospace, and consumer electronics. The SIT1602ACE7-25S is an optimal choice for applications that require precision timing, such as radio communication, digital clocks, medical imaging, and precision timing solutions. Furthermore, its low operating voltage and low power consumption make it ideally suited for wearable devices such as smart watches.ConclusionProgrammable oscillators, such as the SIT1602ACE7-25S, are indispensable components to numerous diversified applications. Due to their compact size, low power consumption, and broad supply voltage range, they are the perfect choice for precision timing solutions in a diverse range of applications.
