Thanks, John, for your reply and opinion. When you recommend a commercially offered
crystal oscillator, I assume you mean a device that has a built-in crystal and osc-buffer
circuitry inside one package. It is my experience that these devices are expensive (a few
dollars each), and my cost-sensitive design right now uses discretes to keep cost down.
The best IC I've seen for my purposes is the Harris/Intersil HA7210 (cost is less than $1
in quantities not including the cost of the crystal), but unfortunately it is rated only to 10 MHz.
I do prefer the "all-in-one" solution, but cost prohibits me. If you know of a vendor
that offers this type of device for less than $2, I would appreciate it.
