552FC000260DGR

Pin Configurable/Selectable Oscillators allow users to customize and select the oscillator frequency and other characteristics at their chosen application. A prime example of such oscillators is the 552FC000260DGR from CTS. This device allows the customer to select the frequency, operating temperature range, startup time, rise and fall times and several other parameters in order to satisfy their current application needs. Additionally, the device features a dual-output IC with a low output ripple and a high stability design, which makes it suitable for high speed clock operation of 400MHz.

The working principle of the 552FC000260DGR oscillator is fairly simple, with a combination of a feed-back oscillator topology, temperature compensation circuitry and manual switching. An oscillator is a circuit design that can maintain an oscillation or alternating output without having to have an external input signal. This is done by having a positive feedback loop at the output which goes back in to the input to maintain a periodic oscillation. In this case, the 552FC000260DGR does this by having a combination of an inductor -- which is an oscillator -- a resistor and capacitors that form a creating the oscillations.

The topology used by the 552FC000260DGR oscillator also includes temperature compensation circuitry. This is to ensure that the oscillation frequency of the crystal remains constant across various temperatures. This circuitry comprises two slightly different kinds of capacitors -- an NPO ceramic type and an NP0/C0G type -- which are attached to the base of the crystal. These capacitors allow the oscillator to maintain its frequency across the specified temperature range, which in this case is between -40 and 125 degrees Celsius.

The 552FC000260DGR oscillator also features manual switching that allows the user to select the desired frequency. This is done by connecting different components to the oscillator’s input pins. Depending on the combination of components connected to the pins, the oscillation frequency can be varied. This allows the user to select the frequency required for the application, which can range from 8MHz to 400MHz.

The 552FC000260DGR oscillator is ideal for applications such as high speed clock operation, microprocessor or Input/Output interface. The device features a high stability design, low output ripple, and a broad frequency range making it suitable for many applications. Furthermore, the pin configurable/selectable design allows the user to customize the oscillator to their specific requirements and select the necessary parameters.
