For most things I do with PICs, the internal 4MHz oscillator is just fine, and saves an I/O pin or two. But I have a few 20MHz oscillators on hand for those times when I need things to go faster. The oscillators that I have are CTS MXO45HST series.

I've never needed to use one until now. Looking at the datasheet, I'm wondering if these are overkill. They can drive 10 TTL loads which might be nice for some applications, but completely unnecessary for driving the clock input on a PIC. One of the things that I like about PICs is that they are extremely low power, and generate negligible EMI. Having this big honking oscillator seems to be generating a lot of noise on the power supply lines. Can anyone suggest some 20MHz oscillators that are very low power?
