OPERATION OVERVIEW
n
System Clock Input
The external clocks which are required to operate the AK4353 are MCKI, LRCK and BICK. The master clock (MCKI)
should be synchronized with sampling clock (LRCK) but the phase is not critical. MCKI is used to operate the digital
interpolation filter and the delta-sigma modulator. The frequency of MCKI can be set by CKS2-0, and can be selected to
half, normal or double speed mode by DFS1-0 (See Table 1).
All external clocks (MCKI,BICK,LRCK) should always be present whenever the AK4353 is in the normal operation
mode (PDN = “H”). If these clock are not provided, the AK4353 may draw excess current and may not possibly operate
properly because the device utilizes dynamic refreshed logic internally. If the external clocks are not present, the AK4353
should be in the power-down mode (PDN = “L”) or in the reset mode (RSTN = “0”). After exiting reset at power-up etc.,
the AK4353 is in the power-down mode until MCKI and LRCK are input.
When the register data of CKS2-0 or DFS1-0 is changed during normal operation, the AK4353 should be reset by PDN
pin “L” or RSTN bit “0”.
