Programmable oscillators are electrical components used in electronic devices to generate electronic signals with a consistent frequency. The SIT3809AI-D-18EG is one such device and is one of the latest offerings from Sitronix. It is a high precision temperature compensated programmable oscillator (TCXO) designed for use in consumer applications where low jitter, low phase noise and low electricity consumption are required.

The SIT3809AI-D-18EG has a frequency range of 0.25 MHz to 12 MHz, and supports both positive and negative pullability. This makes it ideal for use in television, telecommunication and microwave applications. It also features integrated Digital-to-Analog and Analog-to-Digital converters, allowing for remote programmability with the use of an external processor. The device also includes an on-board comparator, enabling simple frequency-to-voltage conversion.

The SIT3809AI-D-18EG has two primary operating modes. In the first mode, called “Mute” mode, the oscillator is disabled and a low-level signal is output. The second mode, called “Output” mode, activates the oscillator, allowing it to generate a frequency-stabilized output signal. The mode is determined by two jumpers located on the top of the device. When these jumpers are in the “Mute” position, the oscillator is disabled. When in the “Output” position, the oscillator is enabled and begins to output a frequency-stabilized signal.

The device’s low-level signal can be programmed and adjusted using on-board trim components. These components are used to adjust the ratio between the fundamental frequency and its harmonics, as well as the output frequency. This allows for the output frequency to be precisely tailored to the application. The device also allows for different gain settings to be configured, allowing for the output signal level to be adjusted.

The SIT3809AI-D-18EG is a low-power device, with power consumption of only a few milliwatts. Its low-power profile makes it ideal for use in battery-powered applications. Its compact size allows it to be used in tight spaces, and its low electrical noise allows it to be used in high-frequency applications. The device is also easy to program and configure, making it suitable for rapid development and deployment in a variety of projects.

In conclusion, the SIT3809AI-D-18EG is an excellent choice for applications where low jitter and low phase noise are required. Its high precision and low power consumption make it an ideal choice for use in consumer applications. Its programmability and on-board trimming allow for precise frequency tuning, and its compact size means it can be used in tight spaces. Finally, its simple programming and configuration make it an easy-to-use and reliable device.
