Pin Configurable/Selectable Oscillators

Pin Configurable or Selectable Oscillators are crystal devices that can be configured (mapped) to a variety of different circuit characteristics as needed by an application. These oscillators are often used in applications such as data communication devices, process controllers, media players, broadcast receivers and industrial automation.The 552BM000649DGR is an example of a pin configurable/selectable oscillator. It is a 4-pin device that is capable of delivering frequencies from 10MHz to 200MHz with efficiencies up to 0.5%. The device is compliant with RoHS standards, and has a CL range of 0-3.3V.The 552BM000649DGR offers an asynchronous oscillator, with an output phase-shift that is selectable between 0, 90 and 180 degrees, as well as phase-shifted and true-phase outputs with selectable output frequency. The device also offers excellent jitter performance, with a noise floor of 35fs.The 552BM000649DGR operates in a variety of applications, such as digital audio and video systems, cellular base stations and networks, servers and other communication systems.The working principle of the 552BM000649DGR is quite simple. It is a PLL (phase-locked loop) oscillator that utilizes a crystal as its source of reference frequency. Once the device is energized, a signal is generated when the reference frequency and the oscillator frequency are in sync. The signal is then output as a square wave that can be tuned to the desired frequency.The 552BM000649DGR oscillator can be controlled by the XTAL input pin, which is the main drive for the oscillator. The CL1, CL2 and CL3 pins are the control pins that are used to tune the frequency. CL1 controls the lower frequency range, CL2 controls the mid-range frequency and CL3 controls the high frequency range.To configure the 552BM000649DGR, the input voltage to the XTAL pin must be set between 0-3.3V. Once the voltage is set, the output frequency can be tuned by adjusting the control pins. The output frequency can be further adjusted by fine-tuning the frequency and phase control parameters.The 552BM000649DGR is a reliable and robust oscillator, offering high levels of frequency stability, low phase noise and excellent jitter performance. It is an ideal choice for applications that require high levels of precision and accuracy.
