i need a clock to drive a sine wave that replaces my f-generator, i tried a hex inverter clock circuit but it didnt seem to be stable , anythin else that would work?

Are sure about that frequency? 420 mhz is in the UHF RF radio band, not many function generators play at that high a frequency. No standard TTL or CMOS logic chips clock that high, usually ECL logic is used up that high.

Maybe f-generator means frequency rather than function. And if he wan't a sinewave, you surely will not get that with any sort of logic device. The best way I can of is to use a VCXO and PLL setup.
