The ABX0112 is a highly flexible XO with selectable
multipliers and two CMOS outputs (one of which can
be selected to be REF_CLK). Thanks to Abracon’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 reso-
nant mode crystals from 13 to 31MHz, and is ideal to
generate 156.25MHz from a standard 25MHz crystal.

Multiplier selector pins. These pins have an internal pull-up that will de-
fault SEL to ‘1’ when not connected to GND.
Selector pin. If DRIVE_SEL is ‘0’, outputs are at high drive. If ‘1’ or not
connected, outputs are standard drive (internal pull-up).
Ground.
CLK1 output is the output of the reference frequency (crystal) after multi-
plication through the Phase Locked Loop.
CLK2 or REF_CLK output (depending on REF_SEL). CLK2 is in phase and
at the same frequency as CLK1. REF_CLK provides the same output as
the crystal reference.
Selector pin. This pin if set to ‘0’ selects REF_CLK on pin 10. If not con-
nected, it defaults to ‘1’ (pin 10 = CLK2). Internal pull-up.
Multiplier selector pins. These pins have an internal pull-up that will de-
fault SEL to ‘1’ when not connected to GND.
