[AKD5394A]
„ Setting of jumper pin
[JP1] (5394_VA) : select the source of power supply for VA pin of AK5394A.
Short : supply from the regulator(T1) on board (default)
(In this case, the jack of “5394_VA” should be open.)
Open : supply from the jack of “5394_VA”
[JP2] (CLK) : select the source of MCLK for AK5394A and AK4103A.
(Excepting the case of receiving from external source, SCLK(BICK) and LRCK for AK5394A and
AK4103A are generated by dividing MCLK which is selected on JP2.)
X’tal : supply from X’tal oscillator(X1) on board. (default)
(Use 24.5760MHz as frequency of X’tal Oscillator.)
BNC : supply from external source through BNC connector(J6)
[JP3, JP4, JP5, JP6] (BNC) : select the connector for analog input.
Short : use BNC connectors(J2, J4).
Open : use XLR(Cannon) connectors(J1, J3). (default)
[JP7] (4103_MCLK) : select the frequency of MCLK for AK4103A. (Note1)
CLK : x 1
HC4040 : x 1/2 (default)
[JP9] (5394_MCLK) : select the frequency of MCLK for AK5394A. (Note1)
24.576M (Note2) : x 1
12.288M (Note2) : x 1/2 (default)
[JP11] (BICK) : select the frequency of SCLK(BICK) for AK5394A and AK4103A. (Note1)
12.288M (Note2) : x 1/2
6.144M (Note2) : x 1/4 (default)
3.072M (Note2) : x 1/8
[JP12] (LRCK) : select the frequency of LRCK for AK5394A and AK4103A. (Note1)
192k (Note2) : x 1/128
96k (Note2) : x 1/256
48k (Note2) : x 1/512 (default)
[JP13] (LRCK1) : select the adjust of the phase of LRCK and SCLK(BICK) for AK5394A and AK4103A.
74HC4040 : supply LRCK without the adjust of the phase of LRCK and SCLK(BICK).
74HC74 : supply LRCK after the adjust of the phase of LRCK and SCLK(BICK) by 74HC74. (default)
[JP15] (IF/5V) : select the source of power supply for digital logic part.
5394_VD :supply from the jack of “5394_VD” (default)
(Use this jack when VD of AK5394A is operated in 3.3V.)
4103_VD :supply from the jack of “4103_VD”.
[JP16] (XTE) : select X’tal oscillator(X1) on board.
Short : not use X’tal oscillator(X1) on board.
Open : use X’tal oscillator(X1) on board. (default)
(Note1) Select the ratio to the frequency of (PORT3, J6 or X1).
(Note2) The value assumed that the frequency of (PORT3, J6 or X1) is 24.576MHz.
