Pin configurable/selectable oscillators are oscillators whose auxiliary circuits and outputs change in configuration, frequency or output format when a voltage is applied to a particular pin. They are used in a variety of applications from the simple AF transmitters of the early 20th century to the high frequency automated systems of today. The 554CE000320DG is one such pin configurable/selectable oscillator, designed for use in general purpose digital applications. It is a dual-polarity, single-ended oscillator, featuring two distinct outputs (V+ and V-). V+ is designed for negative logic whereas V- provides positive logic output. The device has a selectable frequency range of 8MHz to 20.48MHz, and a choice of both Directional Output Hysteresis (DOH) and Programmable Hysteresis (PH) modes, allowing users to select the best output noise margin for their application. The 554CE000320DG includes built-in logic to simplify the programming process and a CLKIN pin that can be used to synchronize it with an external clock. The device also provides a range of user programming options, allowing users to tailor the oscillator performance to their specific application. The unique pin configuration of the 554CE000320DG makes it possible to customize the frequency and logic of the oscillator to the user’s own specifications. The device is programmed using two external program pins. The first pin is VDD, which configures the voltage threshold of the selector. When the voltage applied to the pin is below the programmed value, V+ will be active and the second pin (VSS) will configure the Logic Level and Hysteresis of the selector. The 554CE000320DG can be used in a wide variety of applications, from industrial measurement and control systems to communication and satellite applications. It is ideal for applications in which the frequency and logic of the oscillator need to be changed quickly and easily, or where it is necessary to synchronize or stabilize the oscillation frequency over a long period of time. In addition, the device has low power dissipation and is packaged in a small SOIC-8 package, which makes it easy to integrate into existing systems.
