„ Operation Sequence
1) Set power supply voltages in the fallowing ranges.
[+15]
(green) =+12V∼+18V
[-15]
(blue) = -12V∼-18V
[4358_VD]
(red) = 4.75∼5.25V
[4358_VA]
(red) = 4.75∼5.25V
[4114_5V]
(red) = 4.75∼5.25V(Note2)
[AGND]
(black) = 0V
[DGND]
(black) = 0V
Notes: 1. Each supply line should be distributed from the power supply unit.
2. “4358_VA” should be selected on JP1 (AVDD) and “4114_5V” should be selected on JP7
(4114_5V) if the power supplies of AK4358,digital circuit ,and DIR(AK4114) are not supplied from
the regulator.
2) Set-up jumper pins and DIP switches for desired mode. (See Evaluation Mode Setup.)
3) Power on.
The AK4358 should be reset once by bringing SW1(PDN) “L” upon power-up.
„ Evaluation Mode Setup
Evaluation Modes Options
PCM Mode
1) DIR (Optical Link or BNC input) (default)
2) Feeding PCM data and clocks from an external source
DSD Mode
3) Feeding 1bit data and clocks from an external source
1) DIR (Optical Link or BNC) <default>
The AK4114(DIR) generates MCLK, BICK, LRCK and SDATA from the received data through
PORT1(TORX141: optical link) or J9(BNC). Nothing should be connected to PORT3-5. If the desired input is the
optical connector (TORX141), “TORX” should be selected on JP8(TORX/BNC). If the BNC input is desired,
select “BNC” on JP8(TORX/BNC).
