Introduction

Oscillators, the building blocks of most electronic equipment, are responsible for controlling the emission of electric pulses and have a wide application field in the electronic industry. In this article, we will take a closer look at 7W-18.432MBD-T, examining its application field and analyzing its working principle.

The Application Field

7W-18.432MBD-T is a frequency-dependent voltage-controlled oscillator (FVCO) with an operating frequency between 18.432MHz and 18.956MHz, with its temperature range at a maximum of +125°C. It is mainly used in devices such as single digital tuner devices, cable modifiers, and internet-of-things (IoT) applications where fast and reliable operation is essential.

The oscillator also has a wide range of applicability in higher frequency positioning and communication applications such as Wi-Fi, W-CDMA, WiMAX, and Bluetooth. It is also commonly found in various consumer electronics such as DVD players, HDD (hard disk drive) players, car navigation systems, digital TV tuners, satellite broadcast receivers, digital cameras, and home theater systems.

The oscillator can also be used in medical and industrial applications as well. It is a class 1 device with very high accuracy, frequency stability and dynamic range.

Working Principle

The working principle of this oscillator is quite simple. The device consists of an oscillator core, a voltage-controlled oscillator (VCO) stage and an external capacitor or other external components connected in series or parallel to the VCO to set the desired frequency. The oscillator core has two voltage-controlled terminals, one on the base and one on the collector that are used to control the output frequency. The oscillator core is biased using a constant current source whose value is determined by the input voltage on the base terminal. When the input voltage varies, the bias current also varies, causing the output frequency to vary in accordance with the input voltage.

The capacitor or other external components connected to the VCO are used to set a reference frequency. The oscillator then adjusts its output frequency so that it matches the reference frequency. This reference frequency can be set manually or programmatically to give the desired frequency within the oscillator’s range. The frequency of the output signal can then be varied by varying the input voltage.

Conclusion

7W-18.432MBD-T is an oscillator with a wide range of applications, from consumer electronics to medical and industrial equipment. It is easy to use as it is based on a simple working principle, in which the oscillator adjusts its output frequency to match a reference frequency that can be set manually or programmatically. The oscillator is also highly accurate, with a temperature range of +125°C, frequency stability and a wide dynamic range.
