Function
Control Data Chip Select Pin
Control Data Input Pin
Control Clock Input Pin
L/R Clock Pin
This clock determines which audio channel is currently being input on SDATA pin.
When SMODE pin = “L”, a clock with fs rate is output. This pin is fixed to “L” at
power-down. When SMODE pin = “H”, a L/R clock is input.
Serial Bit Clock Pin
This clock is used to latch audio data. When SMODE pin = “L”, a clock with 32fs or
64fs rate is output. This pin is fixed to “L” at power-down. When SMODE pin = “H”, a
bit clock is input.
Audio Data Input Pin
Digital Power Supply Pin
Digital Ground Pin
Master Clock Input Pin
Reset Pin
When at “L”, the AK4365 is in power-down mode and is held in reset.
The AK4365 should always be reset upon power-up.
