Programmable oscillators have a wide range of applications and are becoming increasingly popular in a variety of industries. Oscillators are used to generate periodic signals of a specific frequency and waveform, and are essential in many electronic systems. SIT1602ACR1-18E is an example of programmable oscillators with multiple features and applications. In this article, we will discuss the application field and working principle of this oscillator.

SIT1602ACR1-18E is widely used for communications, consumer electronics, automotive and industrial applications. This device has a very wide frequency range and can operate from 0.1 Hz to 200MHz. The device has a minimum phase noise of-174dBc/Hz@100 kHz offset, making it ideal for telephone, data and video applications such as modems and optical transceivers. It also has low inject phase noise and minimal spurious signals, making it a suitable choice for high-quality electronic systems such as audio/video systems, broadcast transmitting and receiving, and military communication.

In addition to communication and consumer electronics applications, SIT1602ACR1-18E is also suitable for automotive and industrial applications. It has an internal temperature sensor and requires an external thermistor for temperature compensation for thermal drift. This device is ESD resistant and immune to transient noise, making it reliable for demanding applications. It is also qualified according to the Automotive Electronics Council AEC-Q100 standard and is RoHS compliant.

The working principle of SIT1602ACR1-18E is based on a few different components. The first is the internal crystal that generates a stable reference frequency which is used as the frequency reference for the oscillator. This crystal is then amplified by an amplifier and a filter to produce an output signal. This output is connected to a voltage controlled oscillator (VCO) that is connected to the crystal. When the voltage applied to the VCO varies, the frequency of the output signal varies accordingly. Finally, the output signal is passed through a limiter and an amplifier to produce a strong, clean signal. This oscillator works on the principle of voltage-controlled frequency.

In conclusion, SIT1602ACR1-18E is a highly versatile programmable oscillator that can be used in multiple applications. Its wide frequency range, low inject phase noise, minimal spurious signals and ESD resistance make it suitable for use in communication, consumer electronics, automotive, and industrial applications. Realizing its potential, many users are investing in this device for their projects.
