(2) Master mode
(2-1) A/D evaluation using AK4104 DIT function
PORT1 (DIT) is used. DIT generates audio bi-phase signal from received data and it is output through optical
connector (TOTX141). It is possible to connect AKEMD’s D/A converter evaluation boards on the
digital-amplifier. The MCLK can be generated from crystal oscillator X1 or be input from J11 (BNC) or PORT2
(ROM).
(2-1-1) The MCLK is generated from crystal oscillator X1
Please set JP10 (CLK) “XTL”, open JP5 (LRCK), JP6 (BICK) and JP8 (XTE), short JP7 (MCLK) and JP9
(EXT). In this case, please do not connect anything with PORT2 (ROM).
