AKD5355
Evaluation board Rev.A for AK5355
GENERAL DESCRIPTION AKD5355 is an evaluation board for the portable digital audio 16bit A/D converter, AK5355. The AKD5355 includes the input circuit and also has a digital interface transmitter. Further, the AKD5355 can evaluate direct interface with AKM's D/A converter evaluation board. Ordering guide
AKD5355 --Evaluation board for AK5355
FUNCTION * Compatible with 2 types of interface - Direct interface with AKM's D/A converter evaluation boards - On-board AK4103 as DIT which transmits optical output * BNC connector for an external clock input

Operation sequence
1) Set up the power supply lines. [VA] [VD] [VCC] [AGND] [DGND] (Orange) (Orange) (Red) (Black) (Black) = 2.1 3.6V = 2.1 VA = 5.0V = 0V = 0V : typ. 3.0V, VA pin : typ. 3.0V, VD pin : for digital logic except the AK5355 : for analog ground (including VSS of AK5355) : for logic ground
Each supply line should be distributed from the power supply unit. VD and VA must be the same voltage level. 2) Set up the evaluation mode, jumper pins and DIP switches. (See the followings.) 3) Power on. The AK5355 and AK4103 should be reset once bringing SW1 = SW3 = "L" upon power-up.
Evaluation mode
Applicable Evaluation Mode (1) Evaluation of A/D using DIT (Optical Link) (2) All interface signals including master clock are fed externally. (3) Evaluation of A/D using DIT at MCLK = 384fs (1) Evaluation of A/D using DIT (Optical Link) PORT1 (DIT) is used. On board DIT (AK4103) converts A/D data to an audio biphase signal, which is output through optical connector (TOTX176). It is possible to connect AKM's D/A converter evaluation boards or the digital-amplifier that equips DIR input etc. Nothing should be connected to PORT2. DIT (AK4103) operates at SW3="H". When using an external clock through a BNC connector (J3), select "EXT" on JP4 (CLK) and short JP3 (XTE). JP4 CLK 256-64fs 256-32fs 512-64fs 512-32fs JP6 BICK JP7 LRCK JP3 XTE

(2) All interface signals including master clock are fed externally. All interface signals are provided to the AK5355 through PORT2. AKM's D/A converter evaluation boards can be also connected to PORT2. JP4 CLK 256-64fs 256-32fs 512-64fs 512-32fs JP6 BICK JP7 LRCK JP3 XTE

(3) Evaluation of A/D using DIT at MCLK=384fs. PORT1 (DIT) is used. On board DIT (AK4103) is set to the master mode. The AK4103 provides BICK and LRCK to the AK5355 from an external master clock (MCLK). When using an external clock through a BNC connector (J3), select "EXT" on JP4 (CLK) and short JP3 (XTE). (Refer to a Table 1 3 for the set up of the DIP switch. The master mode should be selected in Table 2.)
