Introduction

Pin Configurable/Selectable Oscillators can provide flexible system timing solutions via integrated dual-output chips of two or more oscillator sub-circuits. 512BBB000644BAG (hereafter referred to as “512B”) is an example of Pin Configurable/Selectable Oscillators and a typical binary coded decimal (BCD) programmable oscillator. This article outlines the application fields and working principles of the 512B oscillator and provides a deeper insight into its use in electronics.

Application Field

The 512B Pin Configurable/Selectable Oscillator is designed to serve a wide variety of applications. It is suitable for many data buses, such as Inter-Integrated Circuit (I2C), Serial Peripheral Interface (SPI) and Serial Synchronous Bus (SSB). The oscillator is also able to serve in many audio, automotive, medical and industrial applications.The 512B oscillator is especially suitable for low noise and low power operation. The oscillator works with a low supply voltage ranging from 1.65V up to 5.5V and can be made to achieve power-saving mode through standby control. This also means it offers an extended service life which appeals to makers who prioritize efficiency and durability in their products.

Working Principle

The 512B Pin Configurable/Selectable Oscillator consist of two independent oscillator circuits with frequency stability of up to +/- 400 ppm. Each one includes a frequency control integer part and a resistor that provides the frequency fine-tuning. The two independent oscillator circuits deliver two different output frequencies that meet the user’s different requirements. Frequency selection is made from the integrated 48-bit BCD code or programming it by using external pull-up resistor.The oscillator features programmable output-level control, allowing users to select TTL/CMOS, Push-Pull or High Current output mode. It has an output frequency range of 8MHz-100MHz and delivers an output amplitude larger than 400mVpp when driven with 5V.

Conclusion

The 512BBB000644BAG is a typical Pin Configurable/Selectable Oscillator that offers flexible system timing solutions through integrated dual-output chips. Its low noise and low power operation, wide application range and extended service life makes it an affordable choice for numerous audio, automotive, medical and industrial applications. Furthermore, its BCD programming combined by an output-level control feature allows users to tailor the oscillator to meet their specific system requirements.
