Pin Configurable/Selectable Oscillators – 552BD000946DG

Pin Configurable/Selectable Oscillators (PCOs) offer one of the most practical methods for oscillator frequency selection and configuration, enabling designers to set their design’s frequency during product development, and also for end-users to select their own frequencies ‘on-the-fly’ during normal operation with the help of a host microcontroller. Cooper Bussmann’s 552BD000946DG is one of the best examples of Pin Configurable/Selectable Oscillators currently available on the market. It has a variety of applications, and a couple of main features which allow designers to easily set the frequency. In this article we take a look at the applications, working principle and features of the 552BD000946DG oscillator.

Applications of 552BD000946DG

The most common application of the 552BD000946DG PCO is as a clock oscillator or system clock. It can be used in battery-operated systems, desktop PCs, embedded industrial automation, medical devices, hand-held instruments and avionics. It can also be used as an oscillator in phase-locked loop (PLL) systems, as well as as an oscillator for phase noise minimized oscillators.

The 552BD000946DG PCO is especially well-suited for embedded applications, since it has a wide range of frequency selection from 32 kHz to 24 MHz, and it can be operated in an extended range of operating temperature from -20 °C to +85 °C. In addition, its footprint is very small and it does not require an external reference or jitter source, making it ideal for low-power and small-footprint applications. Additionally, it can be used in ultra-thin designs as it’s 2.5 x 2.0 x 0.55 mm in size.

Working Principle & Features of the 552BD000946DG PCO

The 552BD000946DG PCO is a fully integrated, low-cost, low-power solution for frequency selection and configuration. The frequency of the oscillator can be programmed using an external microcontroller. The microcontroller can read a 4-bit code from the external pins of the oscillator and set the corresponding frequency. The external pins can be used to select the frequency range, output type, pull-up/pull-down current control, soft-start/soft-stop functionality, and so on. Since it uses an external microcontroller, the oscillator can be programmed in real-time, allowing developers and end-users to easily and quickly select the desired frequency.

In addition, the 552BD000946DG PCO is designed for operation over a wide range of power supplies and operating conditions, making it ideal for industrial applications. It has an adjustable frequency range of 32 kHz to 24 MHz, with a switchable output type (LVCMOS/LVPECL). It also features very low current consumption and features a soft-start/stop pattern to improve reliability.

The 552BD000946DG PCO is also available in both RoHS-compliant and UL94V-0 compliant versions to meet the requirements of industrial applications. The oscillator also features a low-noise design that is optimized for operation over very wide operating temperature ranges.

Conclusion

The 552BD000946DG Pin Configurable/Selectable Oscillator from Cooper Bussmann is a low-cost, low-power solution for designers and users who require configurable frequency selection and configuration. It is designed for a wide range of applications and can be operated in an extended temperature range with a variety of output types. With its adjustable frequency range and small footprint, it is the ideal solution for small-footprint, low-power and ultra-thin designs.
