REFCLK
REFCLK may be used either as an input or as an output. When used as an input, the frequencies, which are
specified in the table above, should be provided by the user. When REFCLK is used as a reference clock for
the internal DCXO-PLL, one of these specified frequencies must be used, to guarantee proper work of the
DELIC.
