I am trying to build a circuit I found online, I'm no expert so I like stuff where the functionality is packaged into a chip of some sort. This circuit simply produces a square wave of 153.6Khz using a chip called exo-3 or exo-3c. The chip has an internal crystal I believe so will be accurate. I cannot find this chip available anywhere (digikey, farnel, jaycar etc) except ebay from the US but postage is expensive. I can hardly find any mention of it on the internet. Is there a replacement for this chip? Is there a simple way to produce 153600Hz squarewave that will be accurate?
Circuit is here, the clock generator is very simple, only the exo-3 and 1 cap. (did I mention I like simple?
