10.DESIGN NOTE
10.1 CDB4352 Revision A.0
D2 has been removed and shorted and R2 has been removed.
The serial audio decode table for S1 is incorrect. ‘01’ should be RJ-24 and ‘10’ should be LJ
The polarity of the silkscreen for Z1, Z2, Z3, Z4, and Z5 is incorrect
The CS4352 revision is A1
10.2 CDB4352 Revision B.0
