I have several sources of 122.88 MHz RF that I could use. They are all nearly sinusoidal 50-ohm single-ended output sources. Do I have to feed this through an LVDL line driver chip? I was thinking of using a small pulse transformer for isolation and simply adjusting the signal level from zero up until the ADC triggered reliably.
If a sinusoidal signal won't work, any suggestions for some simple way to make it into a suitable waveform? - perhaps just diode clipping from a high level?
Thanks
Ken
what are people using for external clock?

Re: what are people using for external clock?
Hi Ken, I am a researcher in NMR engineering. I just got my SDRlab (this board needs an external clock signal 122.88MHz to boot) can you send me some pictures and an BoQ for the components that you bought ?
