Pin Configurable/Selectable Oscillators are an important type of product when it comes to the field of oscillators and digital clock circuits. The 554AH000331DG is an example of an oscillator that is able to be configured and selected according to the users’ preferences. This oscillator is a dual-lockable, differencing-prescaler which is suitable for high frequency applications.

The 554AH000331DG is provides a variety of features that makes it a great choice for applications seeking to replace multiple oscillators with one product. These features include a fully integrated RC circuit, a wide range of output frequencies, and low power consumption. Additionally, these oscillators utilize a constant frequency operation for applications that require low phase noise and jitter.

The key feature of this oscillator is its pin selectable frequency output. The oscillator has sixteen available output frequencies and is able to be selected with a voltage level. These output frequencies range from 1MHz to 30MHz and can be selected based on the needs of the application. Additionally, the feature of variable frequency adjustment allows users to select the output frequency with a small change in the pitch of the oscillation, while making only a small change in the pitch of the oscillation.

The working principle of the 554AH000331DG harmonic oscillator is relatively simple. The pin configuration describes how it works: the two pins on the reciprocal side of the oscillator are configured as either an inherently synchronous or an asynchronous input. When in a synchronous mode, the oscillator will operate in a frequency locked manner, as it is driven directly from the synchronous input. Conversely, when in an asynchronous mode, the oscillator will run freely, without the need for an external oscillator. This allows for a variety of applications including frequency control, clock multiplication, and precalibrated multimedia signals.

The output of the 554AH000331DG can be configured in both open-drain and totem pole formats as well as a slew-rate limited type which increases noise immunity and EMI protection. Additionally, the output drive is selectable through an on-chip resistor and three pins external input which allows the user to select the appropriate level of drive strength to best match the application. This allows the oscillator to meet the EMI and noise requirements of different applications.

The 554AH000331DG oscillator is especially suited for automotive, digital video, and portable media applications due to its wide frequency range and its Pin Selectable Frequency Output. This oscillator can be used to replace multiple oscillators and thus represent a cost-effective technology to reduce board space and cost. The 554AH000331DG oscillator is available in a tiny 3.0mm x 3.0mm TQFN package and is a great choice for applications that require a wide frequency range and exceptional performance.
