FEATURE
The AKD4588 is an evaluation board for the AK4588, a single chip 24bit CODEC that includes two
channels of ADC and eight channels of DAC with internal DIR, DIT. The AKD4588 has the interface with
AKM's A/D converter evaluation boards and AKM's D/A converter evaluation boards. Therefore, it is easy
to evaluate the AK4588. The AKD4588 also has the digital audio interface and can achieve the interface
with digital audio systems via opt-connector or BNC connector.

Analog Inputs
Analog inputs use J10 (LIN) and J9 (RIN) the analog inputs are single-ended. Each channel signal range is
nominally 3.1Vpp@5V. It is proportional to VREFH (Vin=0.6 x VREFH). VREFH is connected to AVDD on the
AKD4588.
Analog Outputs
J2 (LOUT1), J1 (ROUT1), J4 (LOUT2), J3 (ROUT2), J6 (LOUT3), J5 (ROUT3) J8 (LOUT4) and J7 (ROUT4) are
used for analog outputs. The analog outputs are single-ended. Each channel signal range is nominally 3.0Vpp@5V.
It is proportional to VREFH (Vin= 0.6 x VREFH). VREFH is connected to AVDD on the AKD4588.
Digital Inputs
Toslink (TORX176: PORT3) or BNC connector (J12) is used for digital inputs. When Toslink (TORX176: PORT3)
is used, JP3 (RX0) set "OPT" side. When BNC connector (J12) is used, JP3 (RX0) set "BNC" side.
Digital Outputs
Digital outputs use Toslink (TOTX176: PORT2), BNC connector (J11). When Toslink (PORT2) is used for TX1,
JP2 (TX1) set "OPT" side. When BNC connector (J11) is used, JP2 (TX1) set "BNC" side.

Sampling frequency as follows
AK4588 has two methods for detecting the sampling frequency. Clock is compared between recovered clock and X'tal
oscillator by XTL1-0. This information outputs FS0, FS1, and FS2, FS3 bit for detecting the sampling frequency.
The compared X'tal frequency is selected by setting of XTL1-0 (Refer Table 4.) When XTL1-0 is 11, X'tal oscillator is
stopped and the encored sampling frequency information of channel status output FS0, FS1, FS2, FS3, PEM bit of resister
control.

AKM assumes no liability for infringement of any patent, intellectual property, or other right in the

used here:
(a) A hazard related device or system is one designed or intended for life support or maintenance
