Oscillators: 7Q-20.000MCG-T Application Field and Working Principle

Oscillators are electronic components that generate a consistent, periodic waveform. They are used to provide a stable clock signal to computers, telecommunications, data acquisition systems and other electronic systems. Oscillators are also used in radio and television equipment, medical equipment, electronic toys, and electrical instrumentation. Oscillators are commonly built using active components like transistors, and in some cases combination electronic and mechanical components. They can also be built using phase-shift networks or filters and harmonic oscillators.

The 7Q-20.000MCG-T oscillator is a Delco CCD-7Q Voltage Controlled Crystal Oscillator (VCXO) designed for use in applications such as LCD and plasma displays, set-top boxes, satellite receivers, computers, medical equipment, plasma display systems, digital video recorders, and other consumer and industrial applications.

Features and Specifications

The 7Q-20.000MCG-T VCXO has a frequency range of 20.000MHz, a control voltage of 0 to +5 volts and a frequency stability of 0.005%. The phase noise for this oscillator is a tight 80 dBc/Hz at a 1Hz offset from any frequency between 19.6MHz and 20.4MHz. The output circuits will handle TTL or CMOS logic. The module is supplied in Delco\'s robust molded CCD package.

Application Field and Working principle

The 7Q-20.000MCG-T VCXO is used in many professional and consumer applications, such as LCD and plasma displays, set-top boxes, satellite receivers, computers, medical equipment, plasma display systems, digital video recorders, and other consumer and industrial applications. This oscillator is a voltage controlled crystal oscillator (VCXO) that works by having its frequency adjusted by an external voltage source. Voltage is applied to a varactor diode that is in a tuned tank circuit, thus changing the frequency output of the oscillator. The frequency range and stability of the oscillator depend on the values of the components used and the characteristics of the crystal.

The 7Q-20.000MCG-T VCXO is a larger package than some other VCXOs, which means it can be used in larger applications as well as smaller ones. This is accomplished by mounting the module directly on the board and using the included wire lead for the VCSEL. The 3/4" pitch leads provide a space saving option that is less expensive than other designs.

The 7Q-20.000MCG-T is an excellent choice for applications requiring a reliable, low cost, and high performance oscillator. The module is robustly packaged in a plastic enclosure that is designed to be soldered directly onto a PCB, allowing for easy integration into the target device. The oscillator has a voltage controlled frequency range and can be tuned to any desired frequency between 20 MHz and 20.000MHz to meet the needs of many different applications.

Conclusion

The 7Q-20.000MCG-T oscillator is a versatile voltage controlled crystal oscillator (VCXO) that is suitable for use in many applications such as LCD and plasma displays, set-top boxes, satellite receivers, computers, medical equipment, plasma display systems, digital video recorders, and other consumer and industrial applications. The oscillator is housed in a robust CCD package that allows for easy integration into the target device, and its frequency range and stability are excellent. This makes it an excellent choice for applications requiring a reliable, low cost, and high performance oscillator.
