SWITCH PURPOSE POSITION FUNCTION SELECTED
J4 Selects source of voltage
for the CS4344 VA supply
VA
+3.3V
*+5V
Voltage source is the +3.3V to +5V binding post
Voltage source is a +3.3V regulator
Voltage source is +5V binding post
J7 Provides contact points to
measure current
- Measure voltage across these nodes and divide
result by 10 to get current in Amps
S1 Resets CS8416 The CS8416 must be reset if switch S2 is
changed
S2 Sets clock source left Sets clock source for CS4344 (open=J9, *closed
= CS8416)
Sets MCLK ratio of CS8416 right Selects 128x (open) or 256x (*closed)
MCLK/LRCK ratio output for CS8416
