ASAHI KASEI [AKD5353] AKD5353 Evaluation board Rev.B for AK5353 GENERAL DESCRIPTION AKD5353 is an evaluation board for 96kHz 24bit A/D converter AK5353. AKD5353 includes the input buffer circuit and also has a digital interface transmitter. Further, the AKD5353 can evaluate direct interface with AKM's D/A converter evaluation boards. n Ordering guide AKD5353 --Evaluation board for AK5353 FUNCTION * On-board single-ended input buffer circuit * On-board clock generator * Compatible with 2 types of interface - Direct interface with AKM's D/A converter evaluation boards - On-board CS8402 as DIT which transmits optical output * BNC connector for an external clock input 2.75.5V GND CS8402 (DIT) Lch Rch Input Buffer Opt Out AK5353 Clock Generator D/A Data 10pin Header Figure 1. AKD5353 Block Diagram * Circuit diagram and PCB layout are attached at the end of this manual. '99/11 ASAHI KASEI [AKD5353] n Analog Inputs J1(AINL) and J2(AINR) are used. The analog inputs are single-ended and each signal range is nominally 3.0Vpp@5V. It is proportional to VA (Vin=0.6xVA). n Operation sequence 1) Set up the power supply lines. [VA] (red) = 2.75.5V : for VA of AK5353 [3V] (orange) = 2.75.5V : for VD of AK5353 [5V] (red) = 3.45.5V : for logic [AGND] (black)= 0V : for analog ground (including AGND and DGND of AK5353) [DGND] (black)= 0V : for logic ground Each supply line should be distributed from the power supply unit. 2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.) 3) Power on. The AK5353 should be reset once bringing SW4 (5353_PD) "L" upon power-up. n Evaluation mode 1) DIT (Optical Link) 2) Using D/A converter board The AK5353 can be evaluated by distortion analyzer using various AKM's D/A converter evaluation boards. They can be connected by 10pin flat cable via PORT2(DAC/ROM). If the AKD5353 feeds all interface signals (MCLK,BICK,LRCK) to D/A converter board, jumper set up is same as 1) (See above). If all interface signals are fed from D/A converter board, jumper set up is same as 3) (See below). '99/11 ASAHI KASEI [AKD5353] 3) All interface signals (MCLK,SCLK,LRCK) are fed from the external circuit through PORT2 PORT2 (DAC/ROM) is used. JP5,7 and 9 should be open. Selection of JP6 is no care but should not be open.

DIP switch set-up of AK5353 '99/11 ASAHI KASEI [AKD5353] [SW1]: Sets the C-bit of CS8402. (Default is the consumer mode.) This set up does not affect the evaluation of the AK5353. In case of using DIT, need to set it up correctly. For more detailed configurations, please refer to the CS8402 data sheet.
