DESCRIPTION
The PLL601-12 is a highly flexible XO with select-
able multipliers and two CMOS outputs (one of which
can be selected to be REF_CLK). Thanks to Phase-
Link’s advanced Phase Locked Loop technology, it
allows a wide choice of selectable multipliers that
permits the user to achieve useful frequencies from
standard low cost crystals. It accepts fundamental
parallel resonant mode crystals from 13 to 31MHz,
and is ideal to generate 156.25MHz from a standard
25MHz crystal.
