AK4121 Evalation Board Rev.B
GENERAL DESCRIPTION The AKD4121 is the evaluation board for the AK4121, 96kHz asynchronous sample rate converter. This board has the optical connectors to interface with other digital audio equipments and serial interfaces for AKM AD/DA evaluation boards. The AKD4121 achieves quick evaluation of AK4121 Ordering guide

Operating Sequence
Please use the AKD4121 according to the following sequence. 1. Jumper Setting for Power Supply: JP10(3.3V) The JP10 (3.3V) selects power supply of the AKD4121.(3.3V or 5V.) JACK : REG : Providing power supply voltage with 3.3V. Opticlal input is not avaible. Providing power supply voltage with 5V. (3.3V is supplied via regulator on board.)
2. Power Supply Line Setting
Each supply line should be distributed directly from the power supply unit with low impedance connection. 5V or 3.3V : For power supply jack. 5V or 3.3V. (Power supply voltage is selectrd by JP10.) GND : Groung of the board. 0V.
3. DIP Switch and Jumper Pins Setting (refer next page) 4. Power-on(After power is on, SW1 should be reset by setting "L""H" once.)
* The reset is done by SW1 during opertion. The AK4121 is powered down during SW1 is "L".The power down state is canceld by briging the SW1 to "H", at the same time, the AK4121 is reset.
