• Manufacturer Part Number: ak4113
• Description: 192khz 24bit Dir With 6 1 Selector
• Manufacturer: AKM Semiconductor, Inc.

ASAHI KASEI
The AK4113 has two methods for detecting the sampling frequency.
The method is selected by the XTL1-0 bits. The detected frequency is available on the FS3-0 bits.
When XTL1-0 bits = “11”, the sampling frequency is detected by the channel status sampling frequency information. The
detected frequency is available on the FS3-0 bits. In parallel control mode, XTL1-0 bits are fixed to “10”.

Note 12. In professional mode, FS3-0 bit indicates “0001” except for frequency shown by Table 5.
Note 10. At least ±3% range is identified as the value in the. Table 5. In case of intermediate frequency of those
Note 11. In consumer mode, Byte3 Bit3-0 are copied to FS3-0 bits.

two, FS3-0 bits indicate no value. When the frequency is much bigger than 192kHz or much smaller
than 8kHz, FS3-0 bits may indicate “0001” or “1101”.
