Programmable oscillators are electrical circuits used in a variety of applications, from communication and data processing to personal electronics and robotics. They typically consist of an oscillator circuit, a frequency select switch, and a voltage-controlled oscillator. The SG-8003JF-PDC is a dual-frequency programmable oscillator from Crystek Corporation, and is capable of outputting two frequencies from a single oscillator. This type of oscillator offers many advantages over standard discrete oscillators, including higher frequency stability, better temperature stability, faster switching time, and more flexibility in form factor.

The SG-8003JF-PDC is designed for applications such as microwave communication, base stations, Point-to-Point and Point-to-Multipoint radio systems, and medical imaging. The oscillator consists of a simple, three-stage LC oscillator circuit and a voltage-controlled switch using a current-mode logic (CML) logic circuit. The device also includes a reference-frequency divider, allowing for two independent frequencies to be output from the same oscillator circuit.

The programmable oscillator’s operating frequency is selected by adjusting the multi-turn trimmer capacitor in the first stage of the oscillator circuit. The second stage adjusts the output frequency by changing the current flowing in the CML circuit. This current is adjustable through a separate trimmer capacitor, and can be set so as to provide a wide range of frequencies. This allows the user to precisely tune the oscillator to the desired frequency, up to a frequency of 250MHz.

The output of the SG-8003JF-PDC is highly stable and is guaranteed to provide accurate frequencies, even at high temperatures. The temperature stability is further enhanced by the inclusion of temperature-compensated tuning capacitors, which adjust for any temperature-induced changes. The device also has a relatively fast switching time, making it well suited for applications requiring quick frequency switching. In addition, the device is offered in a small 24-pin TSSOP package, making it well suited for embedded applications where space is at a premium.

The SG-8003JF-PDC is a versatile and reliable programmable oscillator, offering a high level of frequency stability and flexibility in a small, cost-effective package. It is a popular choice for applications such as microwave communication and medical imaging, where accuracy and stability are required. With its fast switching time, small form factor, and wide frequency range, the SG-8003JF-PDC is an ideal choice for many different applications.
