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
No errors at this time

SWITCH PURPOSE POSITION FUNCTION SELECTED
J7
Selects source of voltage for
the +5V supplies
+5 V
*+5V_REG
Voltage source is +5 V test point (TP8)
Voltage source is +5 V regulator
J4
Selects source of voltage for
the VD supplies
VD
*+3.3V REG
Voltage source is VD test point (TP2)
Voltage source is +3.3 V regulator
J5
Selects source of voltage for
the VL supply
VL
*+3.3V REG
Voltage source is VL binding post
Voltage source is +3.3 V regulator
J6
Selects source of voltage for
the VA supply
VA
*+3.3V REG
Voltage source is VA test point (TP7)
Voltage source is +3.3 V regulator
J8 Current measure for VD *shunted
When shunt is removed, the voltage can be measured
across a fixed resistance to determine current.
J9 Current measure for VL *shunted
When shunt is removed, the voltage can be measured
across a fixed resistance to determine current.
J10 Current measure for VA *shunted
When shunt is removed, the voltage can be measured
across a fixed resistance to determine current.
J11 Current measure for VA_H *shunted
When shunt is removed, the voltage can be measured
across a fixed resistance to determine current.
S1
Sets clock source, CS8416
clock speed, and CS4352 set-
tings
*1 = open
*2, 3, 4, 5 = closed
position 1: 0 = external clock source, 1 = CS8416
position 2: 0 = 8416 MCLK is 256xFs, 1 = 128xFs
Position 3,4,5: see CS4352 datasheet
S2 Reset - Enables reset for CS4352 and CS8416 when pressed
