Note 3. 32kHz~96kHz for INPUT#2 at Path Mode 0. 8kHz~96kHz at Path Mode 2 and 3.
Note 4. Min = 8kHz at Path Mode 2 and 3.
Note 5. Measured by Rohde & Schwarz UPD04, Rejection Filter= wide, 8192point FFT. Refer Figure 1 and Figure 2.
Note 6. The “0.667” is the ratio of FSO/FSI when FSI is 48kHz and FSO is 32kHz
Note 7. The “6” is the ratio when FSI is 8kHz and FSO is 48kHz.
