Programmable oscillators are widely used in device designs and are divided into digital and analog types. These oscillators provide flexibility and convenience for integrated circuit designers and system engineers. As an example, we will look at the application field and working principle of the SG-9101CG-C05PHDAC programmable oscillator.

The SG-9101CG-C05PHDAC is a programmable oscillator designed and manufactured by Supertex Inc. It is a digitally programmable clock designed to meet the specialized and needs of microcontrollers, digital signal processors (DSPs), and many other low-power applications. This oscillator allows designers to select frequency and duty cycle with a 0.1% accuracy.

The SG-9101CG-C05PHDAC is available in two different versions. The first version is the PLL-based model, which features a wide frequency range from 100 kHz to 3 GHz. The second version, the line-compensated model, features a frequency range from 1 MHz to 4 GHz. Both versions are designed for low-noise operation and are capable of sustained clock output.

The application field of SG-9101CG-C05PHDAC is of wide range. It can be used for various applications such as microcontroller clock generation, digital filtering, digital signal processing, access control, cellular radio, video/audio applications, USB data transmission, as well as industrial automation and many other applications.

The working principle of SG-9101CG-C05PHDAC is based on a standard Programmable Oscillator (PO). This oscillator is designed with a silicon-germanium (SiGe) substrate. The PO has an integrated Temperature Compensated Crystal Oscillator (TCXO) which is connected to the oscillator module via two control pins. The reference clock is locked to the temperature-compensated crystal oscillator. This reference clock is then frequency-locked to a programmable frequency through the programmable frequency register of the oscillator module. The programmable frequency can be changed by changing the values in the programmable frequency register. The frequency value is then used to generate the clock signal which is output from the oscillator module.

The SG-9101CG-C05PHDAC offers the ability to program the frequency range from 0.5 Hz to 4 GHz with an excellent phase jitter performance of 0.2 ps peak-to-peak, excellent reference clock accuracy, and a temperature range of -40°C to +95°C. With these features, this oscillator is ideal for applications that require a wide range of frequencies and high accuracy.

Overall, the SG-9101CG-C05PHDAC can be used in a wide range of applications due to its range of frequencies, excellent phase jitter performance, and reference clock accuracy. The programmable frequency can be changed via the programmable frequency register. With these advantages, the SG-9101CG-C05PHDAC is ideal for applications that require a wide range of frequencies and accuracy.
