When
connecting
word
clock
cables
,
it
is
essential
that
the
receiving
device
be
terminated
at
the
word
clock
input
.
If
word
clock
connections
are
chained
(
not
recommended
but
possible
with
un
-
terminated
inputs
),
a
termination
plug
should
be
connected
to
the
word
clock
input
of
the
last
device
in
the
chain
.
The
WCOUT
/
TERMINATION
LEDs
indicate
whether
each
word
clock
output
is
under
-
terminated
,
over
-
terminated
or
