AK2301A
RESET and Start up sequence
Reset operation starts by low input.
This function is used for the initialization at the power up. Please use MUTEN together with RSTN to
avoid the popping sound from the output until the AK2301A moves into the stable operation.
- Start up sequence
(1) After the power on, please set the RSTN pin to low level for 10msec or more.
(2) Before the first sequence or less than 250
μ
s after the cancellation of reset, please provide the FS and
the BCLK.
(3) Please set the MUTEN pin to low level during the period of the AK2301A’s initialization which is
less than 200msec after the FS and the BCLK provided. The CODEC voice path is established by
releasing the mute function.
