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 (0Ω) 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 (0Ω); R88 = open 3. All clocks are fed through the PORT1. Setting: R54, R55, R56, R58 = open R50, R51, R52 = 100Ω; R53 = 5.1Ω DIP Switch setting [SW1]: AK4115 setting No. Pin 1 2 OCKS1 OCKS0 OFF ON Default Master Clock setting of AK4115 Refer to Table 4 ON OFF Table 2.

OCKS1 OFF ON ON OCKS0 OFF OFF ON MCLK Frequency 256fs @ fs=88.2/96kHz 512fs @ fs=32/44.1/48kHz 128fs @ fs=176.4/192kHz Table 4. MCLK Setting (Default) SW3 setting [SW3] (PDN): Reset of AK4480. Select “H” during operation. External Analog Circuit The differential output circuit and LPF is implemented on board. The differential outputs of AK4480 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 (typ@VREF=5.0V) by BNC. +15 6.8n + 220 AOUTL- + 7 3 2 + 4 6.8n 10k 220 LME49710NA -15 10u 0.1u 6 + 10u 620 620 6.8n + 220 LME49710NA 7 100u AOUTL+ + 6.8n 10k 220 3 + 2 - 100 6 Lch 1.0n LME49710NA 10u 6 0.1u + 1.2k 2 - 4 3 + 7 0.1u 4 680 +10u 1.0n 1.2k 680 0.1u 560 0.1u 560 100u + 10u 10u 0.1u Figure 2.
