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

Note: All input pins should not be left floating. DVDD1-4 must be connected to the same power supply.
Note 1. SPB, CM2-0, INAS, PM2-1, OBIT1-0, TDM, ODIF1-0, IDIF2-0 and CAD0 pin must be changed when the PDN
Note 2. In parallel control mode (SPB pin = “L”), IDIF2-0 pins control all SRC1~3 audio interface input formats.
Note 3. In parallel control mode (SPB pin = “L”), the SMUTE pin controls all SRC1~3 soft mute.
Note 4. In parallel control mode (SPB pin= “L”), DEM1-0 pins control all SRC1~3 de-emphasis settings.

In serial control mode (SPB pin = “H”), the setting of IDIF2-0 pins is ignored. The IDIF[12:10] bits setting is
reflected to SRC1, the IDIF[22:20] bits setting is reflected to SRC2 and the IDIF[32:30] bits setting is reflected
to SRC3.
In serial control mode (SPB pin = “H”), the SUMUTE pin setting is ignored. The SMUTE1 bit setting is
reflected to SRC1, the SMUTE2 bit setting is reflected to SRC2 and the SMUTE3 bit setting is reflected to
SRC3.
In serial control mode (SPB pin= “H”), setting of DEM1-0 pins is ignored. DEM[11:10] bits setting is reflected
to SRC1, DEM[21:20] bits setting is reflected to SRC2 and DEM[31:30] bits setting is reflected to SRC3.

When the PDN pin= “L”, the DV18 pin outputs “L”. Current must not be taken from
this pin. A 1μF (±30%; including the temperature characteristics) capacitor should
be connected between this pin and DVSS. When this capacitor is polarized, the
positive polarity pin should be connected to the VD18 pin.
This pin should be connected to VSS2-5.
When INAS pin = “L”, this pin should be connected to VSS2-5.

These pins must be connected to VSS2-5.
These pins must be open.
