Using my Topward Digital Function Generator 8112 I'm getting widely fluctuating frequency signals (830Hz to 620Hz) which won't settle down even after allowing the unit to warm up and stabilise - some instability somewhere?
In addition the HEF4060BP started to run very hot - too hot to touch - so there may be something wrong with my Breadboard circuit connections??

I've incorporated a 4.9152 MHz crystal in the circuit I am using from the HEF4060B Product data sheet (page 8) - not sure how the component you provide a link for works?
