Evaluation of DAC part used internal DIR
1-1. Digital input (Bi-phase input)
1-1-1. Digital input (Bi-phase input) is used by Optical Link PORT3 (TORX176). And Digital input (Bi-phase
input) is used by BNC connector J12.
1-1-2. Set the part of (DIR/DIT part) control resister software (addr00H: CM10=00) is (Clock Mode is PLL
Mode.)
This mode is able to operate by default setting.
DIP-SW SW2-2 (MASTER) is ON. Audio Digital Interface Format is 24bit left justified at this
time.(Refer datasheet.).
1-1-3. When Digital input (Bi-phase input) is used for RX0 pin, Optical Link PORT3 (TORX176) or BNC
Connector J12 is used. JP3 (RX0) selects this. (Refer Figure 2)

1-2. Analog Output
1-2-1. Analog Output used BNC connector J2 (LOUT1), J1 (ROUT1), J4 (LOUT2), J3 (ROUT3), J6 (LOUT3),
J8 (LOUT), J7 (ROUT4).
1-2-2. Analog Output can be selected of output buffer (OP-Amp: Gain=2) is using or not using.
This is selected JP5 (LOUT1), JP4 (ROUT1), JP10 (LOUT2), JP6 (ROUT2), JP12 (LOUT3),
JP11 (ROUT3), JP16 (LOUT4) and JP15 (ROUT4) (Refer Figure8~9.)
