SG-8002CE-SCM

Programmable oscillators are widely used in many electronic circuits, especially those that require complex switching, timing and frequency control applications. Among all these oscillators, SG-8002CE-SCM is one of the most commonly used oscillators. This article will focus on the application field and working principle of SG-8002CE-SCM.

Application Field

SG-8002CE-SCM is widely used for radio frequency (RF) and clock signal generation in a range of applications including cellular phones, Global Positioning System (GPS), Wi-Fi, Bluetooth, automotive communications, software-defined radio and other wireless communication applications. It is also used to create signals for testing, calibration and validation.

SG-8002CE-SCM features programmable frequency configurations, high output power, and fast settling times, making it ideal for applications that require precise timing and synchronization. Its wide tuning range covers the frequencies most commonly used in cellular, wireless and RF applications.

Working Principle

SG-8002CE-SCM oscillator module is composed of a temperature-compensated crystal oscillator (TCXO) and a microprocessor-controlled voltage-controlled oscillator (VCO). The TCXO is used to generate a reference frequency and its output is connected to the VCO input. The voltage-controlled oscillator is a frequency-\'tunable\' oscillator whose output frequency can be set by varying the control voltage supplied to it.

The microprocessor-controlled VCO then drives the external load, providing the accurate frequency and phase control for the application. The microprocessor also constantly monitors the VCO output to make sure the output frequency is within the specified tolerance. The frequency control loop makes sure the output frequency is always close to its nominal value, even with temperature variations and changes in the load.

In addition, SG-8002CE-SCM also integrates a power-saving feature which reduces the power consumption when the oscillator is in a static state. This feature is beneficial in portable and battery-powered applications, as it helps to extend the battery life.

To summarize, SG-8002CE-SCM is suitable for a variety of applications since its wide tuning range, fast settling times, low jitter and frequency accuracy makes it an ideal choice in applications that require switching, timing and frequency control. In addition, its power-saving feature makes it suitable for applications that are power-sensitive.
