2 / 33 page ASAHI KASEI [AKD4707-A] <KM083602> 2007/01 - 2 - 1. Evaluation Board Manual Operation sequence 1) Set up the power supply lines. [VP] (Orange) = 11.4 ∼ 12.6V (typ. 12V, for VP pin) [VD] (Red) = 4.75 ∼ 5.25V (typ. 5.0V, for VD pin) [VVD] (Red) = 4.75 ∼ 5.25V (typ. 5.0V, for VVD1 pin, VVD2 pin) [VCC] (Red) = 5.0V (for digital logic) [AGND] (Black) = 0V (for analog ground: VSS, VVSS) [DGND] (Black) = 0V (for digital ground) Each supply line should be distributed from the power supply unit. 2) Set-up jumper pins. (See the followings.) 3) Power on. The AK4707 should be reset once bringing SW1 “L” upon power-up. Jumper pins set up [JP1] (GND): Analog ground and Digital ground OPEN: Separated SHORT: Common. (The connector “DGND” can be open.) <Default> [JP2] (VD): Regulator +5V or VD connector OPEN: VD pin is supplied from VD connector. SHORT: VD pin is supplied to regulator +5V. (The connector “VD” can be open.) <Default> [JP3] (VVD): VD connector or VVD connector OPEN: VVD1 and VVD2 pins are supplied from VVD connector. SHORT: VVD1 and VVD2 pins are supplied from VD connector. (The connector “VVD” can be open.) <Default> [JP4] (VCC): VVD connector or VCC connector OPEN: Logic voltage is supplied from VCC connector. SHORT: Logic voltage is supplied form VVD connector. (The connector “VCC” can be open.) <Default> The regulator can be supplied 5.0V to all circuits by shorting JP2, JP3 and JP4 and supplying 12V to VP connector. |
