Pin Configurable/Selectable Oscillators

Pin configurable and selectable oscillators are transferable, accurate, and reliable. These oscillators are particularly suitable for applications requiring flexibility and performance. 554BJ000612DGR is an example of such oscillators which can be easily configured and used with movable and selectable frequencies.

Application Field and Working Principle

554BJ000612DGR oscillator is suitable for a variety of applications such as digital audio, mobile communication, modems and so on. It features a wide frequency range up to 12.8MHz, a small size and low power consumption.

The design of 554BJ000612DGR oscillator is based on a phase-locked loop (PLL) frequency synthesizer. It is composed of a voltage-controlled oscillator (VCO) and a programmable divider. The internal VCO generates a wide frequency range from a single clock frequency. The programmable divider divides this VCO frequency by a user-defined value, and then the divided signal is fed to a phase comparator. This phase comparator in turn adjusts the VCO frequency to the target frequency, which is the divider\'s output divided frequency. The final frequency output is determined by the programmable divider. This programmable divider is controlled by the selection of OE pin and the selection of I&O pins.

OE Pin

The OE pin (Output Enable) is used to control the output signal. When the OE pin is high, a valid signal is output. When OE is low, the output is disabled.

I&O Pins

I&O (Input & Output) pins are used to program the output frequency by setting the divider value. Each I&O pin can be connected to the positive or negative supply voltage to program the output frequency in steps of 32 kHz.

In conclusion, 554BJ000612DGR can be easily configured and used with movable and selectable frequencies. It is a highly cost-effective solution for applications requiring wide frequency range and low power consumption.
