Programmable oscillators are electronic devices that control the frequency of electronic signals. The SG-9101CE-C20PGBBC is an example of a programmable oscillator, and this article will discuss its application field and working principle.
Application Field
The SG-9101CE-C20PGBBC is used in various specialized applications. It is an ideal choice for embedded applications requiring a compact, low power consumption oscillator. These applications include but are not limited to; switches, CPU’s, clocks, consumer electronics, and communication applications.
The SG-9101CE-C20PGBBC is also used in applications where a high degree of accuracy is required. Non-volatile EEPROM allows for user-defined frequencies and temperature compensation using different on-chip devices such as: thermistors, thermocouples, voltage-output temperature-sensing devices, and other online temperature sensors.
The SG-9101CE-C20PGBBC has the capability to automatically adjust with the change in temperature, making it ideal for mobile and automotive applications. Additionally, it offers the flexibility to be used in high reliability applications such as aerospace and military applications.
Working Principle
The SG-9101CE-C20PGBBC consists of a varactor, a temperature-controlled amplifier, and a clock circuit. The varactor is a semiconductor device that adjusts the amplitude of a radio frequency signal, or the output of the oscillator. The amplifier controls the amplitude, and the clock circuit generates the frequency.
The SG-9101CE-C20PGBBC is operated by a micro-controller, which is connected to a programmable oscillator. The micro-controller is used to monitor the temperature, and to adjust the frequency of the oscillator as required, in order to maintain the frequency stability.
The oscillator is divided into two parts; the frequency adjust mode and the temperature compensating mode. In the frequency adjust mode, the frequency of the oscillator is adjusted by adjusting the capacitance of the varactor, in order to achieve the required frequency. In the temperature compensating mode, the micro-controller monitors the temperature and adjusts the frequency as required, to maintain the temperature stability.
The SG-9101CE-C20PGBBC is a low power usage oscillator, and is designed to be highly efficient. It can be used in a wide variety of applications, and is ideal for applications requiring accuracy and stability.
