(The connector “DGND” can be open.) <Default> 2. JP5 (REG-SEL) : AVDD and PVDD of the AK4213 AVDD : AVDD and PVDD is supplied from “REG/AVDD”. REG : AVDD and PVDD is supplied from the regulator. < Default > 3. JP7 (REG) : AVDD and PVDD of the AK4213 OPEN : AVDD and PVDD is supplied from “REG/AVDD”. SHORT : AVDD and PVDD is supplied from the regulator. < Default > 4. JP6 (TVDD-SEL) : TVDD of the AK4213 OPEN : TVDD is supplied from “TVDD” jack. SHORT : TVDD is supplied from “PVDD” (“TVDD” jack should be open). < Default > 5. JP4 (AVC-P-SEL) : Power supply of the “74AVC8T245” TVDD : Power supply of the “74AVC8T245” is supplied from “TVDD”. VD : Power supply of the “74AVC8T245” is supplied from “VD”. < Default > Note : When I 2C bus is controlled via PORT1, the interface voltage should equal to “TVDD”. The function of the toggle SW Up is “H” of the toggle SW, and down is “L” of that. [SW1] (PDN) : Power control of AK4213. Keep “H” during normal operation. SW1 can be set to “H”, after all power supply pins are supplied. Serial Control (I 2C-bus Control Mode) The AK4213 can be controlled via USB interface board packed with the AKD4213-B. Connect PORT1 (CTRL) with PC by 10 wire flat cable packed with the AKD4213-B Connect SCL SDA 10pin Header 10pin Connector 10 wire flat cable for PC AKD4213-B USB I/F Board USB Cable ACK Figure 3. Connect of 10 wire flat cable Note) When I 2C-bus is controlled by uP via PORT1, resistor value of R4 should be properly selected. |
