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

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) PORT1 (TOTX174) is used. DIT generates audio bi-phase signal from received data and which is output through optical connector (TOTX174). It is possible to connect AKM's D/A converter evaluation boards on the digital-amplifier which equips DIR input. JP6 and JP7 should be selected same mode as AK5353. In case of using external clock through a BNC connector (J3), select BNC on JP5(CLK) and short JP4(XTE). JP4 JP5 XTL BNC XTE CLK MCLK JP6 512FS 256FS SCLK JP7 32FS 64FS 128FS LRCK JP9
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).

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. JP4 JP5 XTL BNC XTE CLK MCLK JP6 512FS 256FS SCLK JP7 32FS 64FS 128FS LRCK JP9
