Programmable Oscillators have become essential components in modern electronics, due to their ability to adjust their frequency and phase, depending on the user’s needs. One such example is the SGR-8002JC-PTC Programmable Oscillator. It is a popular choice among electronic device designers, due to its flexibility, convenience, and affordability.

The SGR-8002JC-PTC Programmable Oscillator is a low power, surface mount, low jitter oscillator with a built-in temperature compensation circuit. It has a wide operating temperature range of -40°C to 85°C and is capable of producing frequencies in the range of 0.1 MHz to 133 MHz. The SGR-8002JC-PTC is also available in a standard-size, plastic and ceramic package, giving users the flexibility to choose the most suitable option for their application.

The SGR-8002JC-PTC Programmable Oscillator is ideal for use in applications such as high speed signal transmission, frequency synthesis, and digital signal replication. The device can be programmed to generate a broad range of frequencies and phase delays, depending on the user’s needs. It also offers high-level accuracy and a low phase-noise, making it suitable for applications such as clock generation, phase and frequency modulation, and signal locking. The SGR-8002JC-PTC also features a programmable output voltage, which can be adjusted to a maximum of 4V.

The SGR-8002JC-PTC Programmable Oscillator utilizes a standard two-wire serial programming interface for control. It is powered by a 3V to 5.25V supply and has a maximum operating temperature of 105°C. The device has a low stand-by current of 400µA, meaning that it can be used in low-power applications.

The working principle of the SGR-8002JC-PTC Programmable Oscillator is based on the voltage controlled oscillator (VCO) topology. The device contains a programmable frequency divider circuit and an oscillator loop. The frequency divider circuit is responsible for determining the output clock frequency of the oscillator. The oscillator loop is comprised of an oscillator core, together with an inverter and a pair of transistors that make up the total trans-conductance of the oscillator. The output of the oscillator is then fed back to its input, resulting in constant oscillation. The frequency of the oscillation can be controlled by varying the voltage applied to the VCO core.

The frequency of the SGR-8002JC-PTC Programmable Oscillator can also be adjusted by adjusting the value of the feedback capacitor. The value of the capacitor determines the frequency of the output clock. By varying the value of the capacitor, the user can maintain the desired accuracy of the frequency output. Additionally, the user can also choose between different output configurations, including normal logic output, open-drain logic output, or CMOS output with different output levels.

The SGR-8002JC-PTC Programmable Oscillator combines programmability, accuracy, and low power consumption in a single package. Thanks to its wide operating temperature range and excellent accuracy, this device is becoming increasingly popular in a variety of applications, such as digital clocks, automotive electronics, and communications systems. Its compact design makes it an ideal choice for applications in mobile devices, digital cameras, and other high-tech products.
