Function

Headphone Amp Mute Pin P/S pin = “H” “H” Normal operation, “L” Mute

I Control Data Input Pin P/S pin = “L”

De-emphasis Pin P/S pin = “H” “H” ON 44.1kHz , “L” OFF

I Control Data Clock Pin P/S pin = “L”

Audio Interface Format Pin P/S pin = “H” “H” I2S, “L” 24bit MSB justified

I Control Data Chip Select Pin P/S pin = “L”

I Audio Serial Data Input Pin

L/R Clock Pin This clock determines which audio channel is currently being input on SDATA pin.

Serial Bit Clock Pin This clock is used to latch audio data.

I Master Clock Input Pin

Power-down & Reset Pin

I When at “L”, the AK4366 is in power-down mode and is held in reset.

The AK4366 should always be reset upon power-up.
