AKD4390-SA
AK4390 Sound quality evaluation board Rev.3
General Description
The AKD4390-SA is an evaluation board of the AK4390 (192kHz sampling 32Bit Delta-Sigma DAC). On-board low pass
filters transforming deferential outputs of the AK4390 to single-ended outputs and an SPDI/F receiver accepting practical sound
source from BD, CD or DVD allow users easily to experience its premium sound quality.

■Evaluation mode
1.
DIR(COAX) (default)
The DIR generates MCLK, BICK, LRCK and SDATA from the received data through BNC connector (J7). It is
possible for the evaluation using such as CD test disk.
Setting:R87 = open;
R88 = short (0ohm)
COAX is recommended for an evaluation of the Sound quality.
2.
DIR(Optical)
The DIR generates MCLK, BICK, LRCK and SDATA from the received data through Optical connector
(PORT2). It is possible for the evaluation using such as CD test disk.
Setting:R87 = short (0ohm);
3.
R88 = open
All clocks are fed through the PORT1.
Setting:
-R54, R55, R56, R58 = open
-R50, R51, R52 = 100ohm; R53 = 5.1ohm
■DIP Switch setting
Upper-side is “H” and lower-side is “L”.

■SW setting
[SW3](PDN): Reset of AK4390. Select “H” during operation.
■External Analog Circuit
The differential output circuit and LPF is implemented on board. The differential outputs of AK4390 is buffered by
non-inverted circuit(2nd order LPF, fc=106.4k, Q=0.698, G=+3.9dB). LPF adds differential outputs(1st order LPF, fc=284k,
G=-0.84dB). LME49710NA is used for op-amp on this board that has low noise and high voltage torelance characteristics.
Analog signal is output via BNC connectors on the board. The output level is about 2.8Vrms ([email protected]=5.0V) by BNC.
