OPERATION OVERVIEW
n
D/A Conversion Mode
The AK4357 can perform D/A conversion for both PCM data and DSD data. When DSD mode, DSD data can be input from
DCLK, DSDL1-3 and DSDR1-3 pins. When PCM mode, PCM data can be input from BICK, SDTI1-3 and LRCK pins.
PCM/DSD mode changes by DSDM pin or D/P bit, DSDM pin setting and D/P bit setting are ORed internal. When
PCM/DSD mode changes by DSDM pin or D/P bit, the AK4357 should be reset by RSTN bit, PW bit (PW1=PW2=PD3=”0”)
or PDN pin. It takes about 2/fs to 3/fs to change the mode.

System Clock
1) PCM Mode
The external clocks, which are required to operate the AK4357, are MCLK, LRCK and BICK. The master clock (MCLK)
should be synchronized with LRCK but the phase is not critical. The MCLK is used to operate the digital interpolation filter
and the delta-sigma modulator. There are two methods to set MCLK frequency. In Manual Setting Mode (ACKS = “0”:
Register 00H), the sampling speed is set by DFS0/1(Table 2). The frequency of MCLK at each sampling speed is set
automatically. (Table 3~5). In Auto Setting Mode (ACKS = “1”: Default), as MCLK frequency is detected automatically
(Table 6), and the internal master clock becomes the appropriate frequency (Table 7), it is not necessary to set DFS0/1.
All external clocks (MCLK, BICK and LRCK) should always be present whenever the AK4357 is in the normal operation
mode (PDN= ”H”). If these clocks are not provided, the AK4357 may draw excess current and may fall into unpredictable
operation. This is because the device utilizes dynamic refreshed logic internally. The AK4357 should be reset by PDN= ”L”
after threse clocks are provided. If the external clocks are not present, the AK4357 should be in the power-down mode
(PDN= ”L”). After exiting reset(PDN = “
↑
”) at power-up etc., the AK4357 is in the power-down mode until MCLK is input.
DSD interface signals (DCLK, DSDL1-3, DSDR1-3) are fixed to “H” or “L”.
