AKD4586 Datasheet, PDF (5/46 Pages) Asahi Kasei Microsystems – Evaluation board Rev.B for AK4586

ASAHI KASEI
[AKD4586]
„ Digital Inputs
Toslink(TORX176: PORT2) or BNC connector(J10) is used for digital inputs. Using Toslink or BNC connector is
selected by (JP2).
„ Digital Outputs
TOTX176(PORT2) is used for ADC output, and BNC connector(J3) is used for through data output.
„ Operation sequence
1) Set up the power supply lines. (See “Other jumpers set-up”.)

If JP1 is shorted ,DGND is not needed.
Table 1. Set up of power supply lines
Each supply line should be distributed from the power supply unit
2) Set-up the evaluation modes, jumper pins and DIP switches. (See the followings.)
3) Power on.
The AK4586 should be reset once bringing SW1(PDN) “L” upon power-up.
„ Serial control
The AK4586 can be controlled via the printer port (parallel port) of
IBM-AT compatible PC. Connect PORT1(uP-I/F) with PC by 10-line
flat cable packed with the AKD4586.
Take care of the direction of connector. There is a mark at pin#1.
The pin layout of PORT1 is as Figure 2.
