SRC CHARACTERISTICS
(Ta=25
°
C; AVDD=DVDD=3.3V; AVSS=BVSS=DVSS=0V; data = 24bit; measurement bandwidth = 20Hz ~ FSO/2;
unless otherwise specified.)
Parameter
SRC Characteristics:
Resolution (Note 4)
Input Sample Rate
Output Sample Rate
THD+N (Input = 1kHz, 0dBFS, Note 5)
FSO/FSI = 44.1kHz/48kHz
FSO/FSI = 48kHz/44.1kHz
FSO/FSI = 32kHz/48kHz
FSO/FSI = 96kHz/32kHz
Worst Case (FSO/FSI = 48kHz/8kHz)
Dynamic Range (Input = 1kHz,
60dBFS, Note 5)
FSO/FSI = 44.1kHz/48kHz
FSO/FSI = 48kHz/44.1kHz
FSO/FSI = 32kHz/48kHz
FSO/FSI = 96kHz/32kHz
Worst Case (FSO/FSI = 32kHz/44.1kHz)
Dynamic Range (Input = 1kHz,
60dBFS, A-weighted, Note 5)
FSO/FSI = 44.1kHz/48kHz
Ratio between Input and Output Sample Rate (Note 6)
Note 4. Input data for SRC corresponds to 24bit data. When LSB 4bit data is input, the AK4122 calculates as “0” data
because SRC is 20bit calculation. Therefore, SRC outputs “0” data.
Note 5. Measured by ROHDE & SCHWARZ UPD04, Rejection Filter = wide, 8192point FFT.
Note 6. The “0.33” is the ratio of FSO/FSI when FSI is 96kHz and FSO is 32kHz. The “6” is the ratio of FSO/FSI
when FSI is 8kHz and FSO is 48kHz.
