Programmable oscillators have been around for decades, providing a great way to generate complex waveforms and frequency-controlled signals. The most popular and widely used programmable oscillator is the SIT1602BCE7-28E. It is designed to provide accurate and repeatable time-based signals and is widely used in a variety of applications including test and measurement equipment, medical devices, industrial automation, communications, robotics and control applications. The features and benefits of this device are numerous and include a high frequency tolerance, excellent low noise operation, wide range of output frequency resolution and the ability to interface with a variety of logic families.

The SIT1602BCE7-28E consists of two individual clock oscillators that can be programmed independently to provide various frequencies. Each oscillator consists of a transistor, a resistor and an inductor connected in a \'T\' configuration. The design of the oscillator is based on an active \'T\' topology, which results in an oscillation frequency that is inversely proportional to the values of the components. This allows for a wide operational frequency range and high frequency accuracy.

The oscillators in the device have a minimum frequency resolution of 0.01Hz and can be programmed in the range of 10KHz to 1MHz. A built-in digital-to-analog converter (DAC) is used to set the reference oscillator frequency. The reference and the second oscillator frequencies are then locked together and adjusted by a digital tuning word that is written to the tuning register. The external circuitry connected to the device will then adjust the frequency of the second oscillator to match the reference oscillator, thereby creating a continuously adjustable frequency signal.

The device also provides a variety of output signal formats, including traditional square waves, as well as sawtooth, sinusoidal and triangular wave forms. The output signal can be clocked using a variety of methods, including a crystal oscillator, a voltage control oscillator, a sinusoidal oscillator, or an external clock source. The signal amplitude and signal rise/fall times are programmable and the device can be used in a variety of signal isolation and segregation applications. Other features of the device include over-voltage, over-current and voltage spikes protection, as well as signal monitoring for system failures and other operational issues.

The SIT1602BCE7-28E is a precision and highly accurate programmable oscillator, making it ideal for many different types of applications. Whether it is being used in a test and measurement system, an industrial automation system, a communications system, a robotics system or any other application, the device is well suited to provide quality and reliable performance. For those looking for a reliable and reasonably priced programmable oscillator, the SIT1602BCE7-28E is definitely worth considering.
