I’m having a little problem with terminology. I know that when someone talks about a “resonator” in the electronics sense, the generally mean a ceramic resonator. I also know that these ceramic resonators come by themselves, or in nice little 3 pin packages with included load capacitors.
I need something more frequency-stable than a (ceramic) resonator, so I figure I will need something based on a quartz crystal. I head over to digikey, and find two large categories: “Crystals” and “Oscillators”
What exactly is the difference between these two terms, in the electronics sense? They all look similar to me, and individual data sheets aren’t of much help.
Also, is it common to find a crystal (or oscillator) with internal load capacitors, or will I need to supply these myself?
Thanks,
