electronically configurable or selectable oscillators have many advantages over fixed frequency oscillators. Two primary advantages are their versatility and accuracy. Oscillators configured by pins, such as the 512MBA000230BAG, are a popular choice for applications needing the most accurate frequency tuning, over a wide frequency range, and relatively wide bandwidths. Oscillators with pin selectable resistor divider networks allow for accurate frequency tuning based on values chosen by the user. These networks may cover a wide range of frequencies, typically from around 1kHz to several hundred MHz. A single oscillator can be used to generate multiple frequencies within its capability range when used with an analog voltage input.

The 512MBA000230BAG is a pin configurable/selectable oscillator composed of three main elements; a reference oscillator, a prescaler, and a resistor divider network. The reference oscillator provides a stable base frequency to the circuit. The prescaler divides the frequency by a power of two, and the divider network is responsible for fine tuning the desired frequency. To adjust the oscillator to different frequencies, discrete resistors of known values must be connected to the appropriate pins. Generally, to increase the frequency, a pull-up resistor is attached to the pin, while a pull-down resistor should be used to decrease the frequency. The resistors must be carefully chosen in order to achieve the desired accuracy.

In many applications, the user must also consider the accuracy of the oscillator. The 512MBA000230BAG is rated for stability to +/-25ppm over its operational frequency range, and accuracy is further improved when the oscillator is used with external resistor dividers. For applications where accuracy and frequency stability are paramount, the 512MBA000230BAG is a great choice. Additionally, this oscillator offers a low power consumption of approximately 10mA, a wide frequency range from 60MHz to 1GHz, and a one-time programming capability that means the frequencies need not be changed between power cycles.

In conclusion, pin configurable/selectable oscillators, like the 512MBA000230BAG are ideal for applications that need the most accurate frequency tuning, over a wide frequency range, and relatively wide bandwidths. They are also beneficial to applications that require accuracy and frequency stability. The 512MBA000230BAG oscillator offers a one-time, low-power programming capability, wide frequency range, and relatively higher accuracy over its operational range.
