„ Sampling frequency as follows
AK4589 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 ON(1,H),ON(1,H),
X’tal oscillator is stopped and the encored sampling frequency information of channel status output FS0, FS1, FS2, FS3,

„ Analog Inputs
BNC connector J10 (LIN),J9 (RIN) are used for analog inputs on the AKD4589-B. Analog inputs are single-ended
and input ranges of each channels are nominally 6.2Vpp@5V. (Input ranges of each channels of analog inputs of
AK4589 device are nominally [email protected],for the resister division,the value which analog input level of
Evaluation Board is devided by two becomes to analog input level of AK4589 device on the AKD4589-B. So, input
ranges of AKD4589-B becomes to 6.2Vpp@5V,twice of the value in the case of AK4589 device. Input range of
AK4589 device is proportional to VREFH (3.1=0.62 x VREFH). VREFH is connected to AVDD on the
AKD4589-B.)

Gain of analog input circuit is
330/(330+330) = -6.02dB.
Therefore input level for this board is
+0.80dBV(=3.1Vpp)+6.02dB
= +6.82dBV = 6.20Vpp = 2.19Vrms.
2) S/N of op-amp circuit (Theory: BW=20k+A)
Non-inverting amp is implemented on board. The output noise level of op-amp circuit is
-126.01dBV = -132.54dB (0dB=+6.53dBV).
S/N of ADC is
101.6dB (measurement).
Therefore total S/N of op-amp circuit and ADC is
101.60dB (measurement: 101.6dB)

Red letter indicates “H” or “1” and blue letter indicates “L” or “0”.
Blank is the part that is not defined in the datasheet.
„ Attention on the operation
Input data to all boxes when you have set up “Function1 dialog” or “Function2 dialog”. An “attention dialog” is indicated
if you input data or address that is not specified in the datasheet or you click “OK” button before you input data. In that case
set up the dialog and input data once more again. These operations does not need if you click “Cancel” button or check the
check box.
