Hi all,
1) How to select a high speed(1.5GHz) I/O circuit?
2) How to equate the phase noise to jitter in VCO if no using integrating the phase noise~frequency offset curve. In other words, if you only know several offset frequency's phase noise,for example,-100dBc/Hz@100KHz,-120dBc/Hz@600KHz and -140dBc/Hz@1MHz,How to get the corresponding jitter(period jitter in RMS format or cycle-to-cycle jitter in RMS format)?
3) What's the type of jitter described in products' datasheets if there is no notes?Period jitter or cycle-to-cycle jitter?
Thank you very much.
