Pin Configurable/Selectable Oscillators are a type of clock oscillator that can be selectively configured to achieve various timing, jitter, and reliability. The 552EJ000412DGR is a pin configurable oscillator designed to meet the stringent requirements of industrial, medical, and aerospace applications. This oscillator offers a wide range of frequency and accuracy options, as well as an optional built-in holdover circuit for excellent long-term stability.

The 552EJ000412DGR oscillator features a wide range of input and output frequency selections, with ranges from 1 Hz to 200 MHz. It has a wide selection of output waveform options, including LVPECL, LVDS, and HCSL. The device also has an optional selectable active loop bandwidth feature, which improves jitter performance and allows for tighter tolerances. The active loop bandwidth feature allows for an even wider range of frequencies and improved accuracy of time keeping.

The 552EJ000412DGR is designed to operate over a wide temperature range, from –10ºC to +105°C. It is RoHS compliant and available in a variety of form factors, including surface mount (SMT), through-hole (THT), and most recently drop-in cavity packages.

The 552EJ000412DGR uses a tunable circuit to achieve various output frequencies. The circuit consists of a varactor diode, a range of capacitors, resistors, and inductors. The varactor diode allows for the capacitance of the diode to be varied, which changes the frequency at which the oscillator resonates. By changing the capacitance of the varactor diode, the frequency of the oscillator can be adjusted over a wide range.

The 552EJ000412DGR also features an optional holdover circuit that allows for improved long-term stability. The holdover circuit uses a digital temperature compensation circuit to adjust for changes in oscillator frequency due to temperature variation. It also features a digital frequency monitor circuit that continuously monitors the oscillator frequency and can output an error signal when a frequency drift occurs.

The 552EJ000412DGR is an excellent choice for applications that require precise frequency control and improved selectivity. Its wide range of frequency and accuracy options, along with its optional holdover circuit, make it an ideal choice for industrial, medical, and aerospace applications.
