[ARC5] Square wave oscillators

[Bruce Long]

These programable oscillators use a simple digital freq synthesis scheme and I expect the signal quality could be really bad. Example they generate a specific freq by alternating outputing freq A which is somewhat above the desired freq and freqB somewhat below the right freq in the right proportion to produce the desired freq on average. Digital devices don't

Looking for something else on ebay I found a seller that has "1khz to 33MHZ Oscillator module" for less than $10.

This device produces a square wave.  I am very aware that such oscillators are very rich in harmonics but if it is substituted for a crystal (just the crystal) in an older design RF oscillator circuit, how well will it work?

Thanks!
