   For a phone switch I am currently developing I am looking for a chip that:
   Will generate two sine-wave tones simultaneously
   Is computer programmable (height of tones, and preferebly amplitude)
   Works from 100 to 3000 Hz


	Greetings. Have you considered the AY-3-9128 (I believe).
	It's a PSG (programable sound generator) with 3 seperate
	channels. I found it simple to program and the output
	were well within 100-3000 Hz I think you can get it at
	Radio Shack (expen$ive) or Jameco or DigiKey...

	You can find specs in any Radio Shack cross reference
	paper back.

	Take care.
