be
seen
as
IPOD_AUDO_L
and
IPOD_AUDIO_R
this
is
driven
thru
the
NJM2114
op

amp
at
IC201(A/B)
before
arriving
at
the
DG413
analogue
cmos
chip
at
location
IC200
(A/B)
this
switch
allows
for
the
routing
of
either
audio
from
a
docked
iPod
or
from
the
external
path

is
the
YUV

these
signals
are
derived
directly
from
the

can
be

Default

is

switched
when
an
“Arcam”

is
inserted

KLEER
and
DSP
All
audio
signals
are
routed
thru
the
Analog
Devices
DSP
chip
at
location
IC400
allowing
for
not
only
the
High/Low
pass
filtering
of
channels
for
the
power
amp
stage
but
also
bespoke
audio

–
a
Wolfson
WM8805
running
form
a
ref
11.2896Mhz
clock
is
used
primarily
for
Jitter
reduction
for
the
Kleer
input
chip
at
Location
IC407
–
it
is
important
to
note
that
the
Kleer
Chip
is
a
receiver
or
transmitter
the
Kleer
chip
is
under
control
of
the
micro
at
position
U301
the
receive
/
transmit
circuit
can
be
seen
on
the
R.F
amp
circuit.
Data
for
transmission
from
a
docked
or
external
source
can
be
seen
coming
from
the
DSP
as
SDATA_DSP_OUT.
The
E2PROMS
at
locations
IC405
and
IC406
are
used
to
store
transmit
/
receive
lock
history.
RF
AMP
Think
of
this
stage
as
a
transceiver
i.e
it
will
both
send
and
receive
information
from
the
external
target
the
stage
uses
toggle
switches
to
effective
switch
the
between
the
transmit
and
receive
stages.
