Parameter
Audio Interface Timing (Master mode)
Power-Down & Reset Timing
Note 7. “L” time at I
Note 8. SCLK= SCLK/SCLK4/SCLK5, LRCK= SCLK/LRCK4/LRCK5 unless otherwise specified.
Note 9. SCLK rising edge must not occur at the same time as LRCK edge.
Note 10. SCLK= SCLK4/SCLK5, LRCK= LRCK4/LRCK5.
Note 11. This value is when fs=48kHz or 44.1kHz. When fs=32kHz, L=(5/9x100)% and H=(4/9x100)%.
Note 12. The AK4141 can be reset by bringing the PDN pin = “L”.
Note 13. This cycle is the number of LRCK rising edges from the PDN pin = “H”.
Note 14. Data must be held for sufficient time to bridge the 300 ns transition time of SCL.
Note 15. I
MS0952-E-00
