System Reset
The AK4394 should be reset once by bringing PDN = “L” upon power-up. The AK4394 is powered up and the internal timing starts
clocking by LRCK “
-
” after exiting reset and power down state by MCLK. The AK4394 is in the power-down mode until MCLK and
LRCK are input.
n
Power-Down
The AK4394 is placed in the power-down mode by bringing PDN pin “L” and the anlog outputs are floating (Hi-Z). Figure 6 shows an
example of the system timing at the power-down and power-up.

Notes:
(1) The analog output corresponding to digital input has the group delay (GD).
(2) Analog outputs are floating (Hi -Z) at the power-down mode.
(3) Click noise occurs at the edge of PDN signal. This noise is output even if “0” data is input.
(4) The external clocks (MCLK, BICK and LRCK) can be stopped in the power-down mode (PDN = “L”).
(5) Please mute the analog output externally if the click noise (3) influences system application.
The timing example is shown in this figure.
(6) DZF pins are “L” in the power-down mode (PDN = “L”).
