    CML buffer advantages for VCO

    Hello,
    I would like to ask which are the advantages about using cml as vco buffers.

    Thanks in advance!

    CML = current-mode logic?

    Constant-current operation makes less ground noise on
    switching edges, whose ringing can make random or
    cyclostationary phase noise.

    If trace impedances are low and traces short, CML can
    be one of the fastest logic interfaces. However CML is
    not exactly standardized, meaning you have to own
    both ends (or get lucky). On-chip, probably a winner.

    PECL and LVDS are not bad alternatives (better than
    bang-bang CMOS anyhow).
