    What is an RF Oscillator in a driver IC for? How fast can a diode switch on/off

    This data sheet mentions an RF Oscillator https://media.digikey.com/pdf/Data%20Sheets/Atmel%20PDFs/ATR0885_Summary.pdf It says "An on-chip, low-EMI RF oscillator is available to reduce laser mode hopping noise". What does this mean? I have a phr-803t optical head from an xbox DVD player and...

    Question about how voltage supply affects constant current driver

    Hello, first post here. I'm not very knowledgeable in electrical engineering and haven't been able to clarify my understanding of a constant current driver. I have set up a typical constant current source with an LM317 and can set it to output the current I want. The circuit I followed uses a...
