Pin Configurable/Selectable Oscillators

Pin configurable/selectable oscillators are highly advanced devices that allow for a variety of configurations to be programmed into a device using only a few pins. The DSC6121HI2A-00AQ is an example of such a device, and in this article, we will explore its application field and working principle. The DSC6121HI2A-00AQ is a voltage-controlled oscillator (VCO) which can be used in a variety of applications ranging from telecommunications and networking to military and aerospace systems. It features a wide tuning range of 200MHz to 2GHz and a low power consumption of less than 4 mW. The device is also RoHS compliant and has a variety of package options.The pin configurable/selectable system of the DSC6121HI2A-00AQ is based on two pins, a control voltage pin (VCTL) and a select pin (SEL). The control voltage pin is used to set the frequency/pulse width of the oscillator and the select pin is used to configure the device for different applications. By using an external digital signal processor (DSP), signals can be fed into the control voltage pin and the select pin, allowing for easy programming and configuration of the device.The working principle of the DSC6121HI2A-00AQ relies on the combination of a tuned port and double-tuned resonator. The tuned port acts as the input, allowing a signal to be fed into the oscillator. The double-tuned resonator then amplifies the signal, causing it to oscillate at a frequency determined by the control voltage pin. When the select pin is set, this changes the oscillator’s parameters.In addition to its pin configurable/selectable system, the DSC6121HI2A-00AQ also features a temperature compensation circuit that keeps the oscillator operating within its operating conditions over its temperature range of -55°C to +125°C. It also has additional features such as a fast-startup lock and disable mode, which allow the device to power up quickly and be disabled when not in use.In summary, the DSC6121HI2A-00AQ is a voltage-controlled oscillator that can be easily configured and programmed using only two pins. Its pin configurable/selectable system, temperature compensation circuit, and additional features make it an ideal choice for a variety of telecommunications and networking applications.
