511QAA-BBAG

Programmable oscillators are circuits that generate a periodic and almost sinusoidal output signal, whose characteristics can be adjusted and programmed without requiring modifications or replacements in its circuitry. The 511QAA-BBAG application field and working principle falls into this category of circuits.

The 511QAA-BBAG model is a Voltage Controlled Oscillator (VCO). It has possible frequency ranges between 10MHz and 12GHz, while its tuning sensitivity varies between 0.1V/GHz to 6V/GHz, depending on the specific application. The programming resolution of the 511QAA-BBAG model can go up to 1mHz, providing excellent precision characteristics.

In terms of size, the 511QAA-BBAG is a miniature and portable oscillator, measuring just 5.5mm x 5.8mm x 2.2mm, and weights 0.47g. This makes it an excellent candidate for embedded applications in harsh environments, where small size and robustness are needed.

The functioning principle of the 511QAA-BBAG is simple yet efficient. An Input Voltage V_CTRL is fed to the oscillator, which is equal or lower than 3.3V. A Voltage Controlled Crystal (VCXO) oscillator multiplies this input voltage by a quarter. This voltage-controlled crystal is set to a default frequency that can be adjusted by altering the input voltage V_CTRL.

The output frequency is thus the product of the multiplication of the quarter frequency and the value of the input voltage. As an example, if the quarter frequency is 100MHz and the input voltage is 3V, the output frequency of the 511QAA-BBAG oscillator will be 300MHz.

Aside from the primary input voltage, there are other input signals that can also be used to precisely tweak the output frequency. The Crystal Load Capacitance (CLC) can be adjusted so as to adjust the crystal\'s frequency. There are also other variables that can be adjusted, such as Series Resistance (RS) and Series Inductance (LS) according to the specific needs of the application.

In summary, 511QAA-BBAG application field and working principle is a Voltage Controlled Oscillator (VCO) that can generate output signals with frequencies between 10MHz and 12GHz, and with a programming resolution of up to 1mHz. It is an ideal oscillator for applications where small size, robustness, and programming complexity are a priority.
