SG-8003CE-SDM

Programmable Oscillators are devices made up of components such as resistors, capacitors and inductors, which enable them to generate a signal at a specific frequency. SG-8003CE-SDM is one type of programmable oscillator specifically designed for use in a variety of applications. Its main advantages are its high frequency stability, high mechanical stability, and extremely low 0.02ppm frequency variation over the entire -40 to +85⁰C temperature range.The SG-8003CE-SDM utilizes an embedded Pre-set Crystal/VCXO and a Phase Locked Loop (PLL) to generate the frequency. The PLL includes a Voltage Control Oscillator, a phase detector, a loop filter, and a charge pump. In the PLL, the control voltage is used to adjust the output frequency. The frequency is determined by the type of crystal used and the voltage applied to the crystal.When the SG-8003CE-SDM is powered on, a CMOS circuit generates a start-up signal which enables the embedded pre-set crystal/VCXO. The PLL then locks onto the crystal, producing a low jitter clock signal. The range of frequencies that the oscillator can produce can be programmed using an external control voltage source. The control voltage required to generate each frequency is determined by an external capacitor or resistor (depending on the model).The SG-8003CE-SDM is therefore an ideal choice for a wide range of applications, such as mobile telecommunications, automotive systems, network clock generation, set-top boxes, digital audio equipment and many more. Its high frequency stability makes it suitable for systems requiring precise frequency control, such as base stations and digital scanners.The SG-8003CE-SDM is also highly reliable and robust, with a wide operating temperature range of -40 to + 85⁰C, shock resistance up to 1,000G and vibration resistance up to 15G. Furthermore, the SG-8003CE-SDM is designed to have a very low EMI/RFI level, meeting all international standards.In conclusion, the SG-8003CE-SDM is an extremely useful and reliable programmable oscillator, offering a wide range of features such as high frequency stability, wide temperature range and low jitter. Its low EMI/RFI level and shock resistance make it suitable for many different applications, making it a great choice for engineers looking for a highly reliable solution.
