om...
I have XR2206 function generator IC. Output frequency is is determined
by capacitor and resistor. Documentation is clear and test circuit
simple. However i cant reach 1 MHz. !! I can't reach above 860 kHz.
Component values are exactly as they need to be for 1MHz.

What's your R and C?
Any parasitic capacitance or inductance (long wires) in your setup?
