National Semi used to make a chip (MM5369) that was designed specifically for that task, but it's long out of production. I don't know of any off-the -shelf 60Hz generators, but it's pretty easy to build one. Here are a couple of web pages that will generate a 60Hz crystal controlled signal. http://electronicsmaker.com/em/admin/pdf/circuit_idea/60Hz%20CRYSTAL%20CONTROLLED%20TIME%20BASE.pdf http://www.electronicecircuits.com/electronic-circuits/50hz-60hz-frequency-generator-circuit-using-crystal-oscillator Accuracy of the generated 60Hz will depend, of course, upon the tempco of the crystal, the complete oscillator circuit itself, and on the accuracy to which you adjust the oscillator's frequency.
