• Manufacturer Part Number: AK4129
• Description: 6ch 216kHz / 24-Bit Asynchronous SRC
• Manufacturer: AKM [Asahi Kasei Microsystems]

MS1173-E-01
• Serial Control Mode (SPB pin = “H”).
•Asynchronous Inputs Mode (INAS pin = “H”).
• OMCLK/XTI Input=
• Input PORT: Slave mode, IBICK1~3 lock mode (64FSI)
• Output PORT: Master mode, 24 bit MSB justified.
• Dither = OFF, De-emphasis filter can be set by registers. PM2/1 pin= “H/L” (6ch original mode)
C1= 0.1μF
C2=10μF
C3=1μF± 30%
Notes:
- All digital input pins should be not left floating.
- VSS1 -5 must be connected to the same ground plane.
- Connect a 1μF (± 30%; including temperature characteristics) capacitor between the VD18 pin and DVSS. When

this capacitor is polarized, the positive polarity pin should be connected to the VD18 pin.
Input Audio Interface Format can be set by registers.
