    All About Oscillating Crystals - Quartz or Oscillator?

    nwieland
    A quartz crystal alone does not make a signal. If you want to use it as a reliable time base, you need a suitable oscillator circuit. These can either be developed yourself or bought together with the oscillator crystal as a ready-made oscillator. This is usually faster and more practical than reinventing the wheel.

    When creating an electronic-based product, engineers must ensure that their designs are EMC compliant before they can be released. This can potentially mean lots of rework if it isn’t addressed until later in the design process, especially if there is a failure to meet the standards. EMI filters can be a great solution for managing unwanted noise if they are integrated early in the design.

    An optocoupler, also known as photocoupler or opto-isolator, is a device which can transfer an electrical signal across two galvanically-isolated circuits by way of optical coupling. Unlike transformers or capacitors, which can only transfer AC signals across the isolation barrier, optocouplers can transfer both DC and AC signals alike. This makes them very popular in applications like isolated power supplies or isolated…
