Programmable Oscillators are an important class of ICs in the field of electrical engineering and have been used extensively for numerous applications over the years. The SIT1602BCE3-25S is an example of such a programmable oscillator which has multiple application fields and working principles.

The SIT1602BCE3-25S is a low-power programmable oscillator that is designed to generate a frequency output of between 8 kHz and 25 MHz. It is based on a PLL (Phase Locked Loop) architecture which has been designed to keep the frequency steady and output stable. This oscillator is designed to operate over a voltage range between 1.65V and 3.3V and features a Programmable Output Mode which allows the user to select either a frequency output, or a duty cycle output. The Programmable Output Mode also allows for the synchronization of multiple SIT1602BCE3-25S devices.

SIT1602BCE3-25S is equipped with a wide range of features and functions that makes it ideal for use in low-power applications such as medical devices, portable appliances, test and measurement equipment, entertainment, communication, industrial control and consumer electronics. Its programmable output mode also makes it suitable for applications such as RF (Radio Frequency) design, frequency synthesis, signal modulation and signal mixing. The oscillator has a fast start-up time of less than 10 µs and has a wide operating range of -40° C to +85° C thus making it well-suited for use in industrial and automotive environments.

The working principle of the SIT1602BCE3-25S programmable oscillator is based on a PLL architecture consisting of three basic elements—an oscillator, a phase comparator, and a loop filter. The oscillator outputs a signal with a frequency that can be predetermined by the user, and this signal is sent to the phase comparator. The phase comparator then compares this signal with the reference signal, and sends the difference to the loop filter. The loop filter then filters the output of the phase comparator to generate the output frequency. The output frequency is regulated by the feedback from the phase detector and is determined by the reference frequency of the input.

The SIT1602BCE3-25S programmable oscillator is a cost-effective, low-power solution for many design requirements. It is a highly versatile device that is suitable for a wide range of applications where precise frequency control is required. Its programmable output modes provide additional flexibility for the user and allow for fast, accurate and reliable frequency generation at a price point that is affordable for most designers.
