Programmable oscillators are devices that feature preset, user-programmable frequencies, outputs and voltage settings. They provide easily-configurable interface capabilities to control frequency, voltage, and other settings over a broad frequency range, allowing for more accurate, efficient and reliable control over digital-controlled applications. Among them, the SG-9101CA-C07SHDAC type of programmable oscillator is particularly reliable and is suitable for various application fields, such as signal conditioning, data acquisition, power supply design, signal transmission and signal converters, to name a few.

The SG-9101CA-C07SHDAC programmable oscillator has a wide range of output frequency and voltage settings. In general, the Voltage Control Oscillator (VCO) version of this type oscillator can provide outputs in the frequency range of 315MHz to 6GHz, offering up to ±10% frequency variation with the addition of an external power supply. This makes it ideal for applications such as wireless communication and cable TV transmission.

In terms of output voltage, the SG-9101CA-C07SHDAC has a wide range of available outputs ranging from 0.3 to 5.3V. This allows for applications such as signal conditioning and oversampling designed for audio and/or video signals. Furthermore, due to its wide operating temperature range of -40°C and +125°C, the SG-9101CA-C07SHDAC is especially suitable for applications working in extreme temperature conditions.

From a construction point of view, the SG-9101CA-C07SHDAC oscillator features a robust construction. It is designed using advanced CAD/CAE tools and utilizes an all-surface mount technology for high frequency stability. Additionally, the oscillator’s 14-bit temperature setting pin increases its operating temperature range, making it suitable for a number of applications including automotive, telecommunications and industrial systems.

The working principle behind the SG-9101CA-C07SHDAC oscillator is based on the VCO (Voltage Control Oscillator) technology. This type of oscillator is basically composed of three elements: the voltage-controlled oscillator (VCO), the charge pump and the voltage-controlled capacitor (VCC). The VCO is a low-frequency sine wave generator with two output terminals and three control inputs: a voltage control input, a temperature control input, and a frequency control input.

The charge pump allows for the storage and conversion of electricity from one source to another. It regulates the output current and utilizes a capacitor across the output terminals to store and deliver the charge from one input to the other input. The VCC is a variable capacitor which can be directly programmed using the voltage control input and is used for fast frequency tuning. In addition, the temperature control input acts as a bias voltage source for fast frequency adjustment.

The working principle of the SG-9101CA-C07SHDAC can be described as follows: the voltage control input is used to VCO, while the temperature control input helps to adjust the operating temperature range. Furthermore, the frequency control input also affects the output frequency and is used to stabilize the frequency over temperature variations. Finally, the charge pump is used to store and deliver the charge from one input to the other and regulate the output current.

The SG-9101CA-C07SHDAC is a reliable and versatile programmable oscillator which can help to reduce complexity and cost in a variety of application fields. It has a wide frequency range, high frequency stability, and its temperature control input greatly reduces the risk of frequency drift. Furthermore, its advanced features allow for its use in various applications that require fast frequency tuning, signal conditioning and data acquisition.
