For the best performance,decoupling and filtering capacitors should be located as close to the device package as possible
Additional parallel capacitors(typically 0.1 μF) can be used, larger value capacitors(typically 10 μF) would also help

4. CLOCK MODES AND SAMPLING FREQUENCIES
The device supports two types of clocking: standard audio clocks (256Fs, 384Fs, 512Fs, etc), and
USB clocks (12/24 MHz).
According to the serial audio data sampling frequency (Fs), the device can work in two speed
modes: single speed mode or double speed mode. In single speed mode, Fs normally ranges
from 8 kHz to 48 kHz, and in double speed mode, Fs normally range from 64 kHz to 96 kHz.
The device can work either in master clock mode or slave clock mode. In slave mode, LRCK and
SCLK are supplied externally, and LRCK and SCLK must be synchronously derived from the
system clock with specific rates. In master mode, LRCK and SCLK are derived internally from
device master clock.
5. MICRO-CONTROLLER CONFIGURATION INTERFACE
The device supports standard I
2
C micro-controller configuration interface. External micro-
controller can completely configure the device through writing to internal configuration
registers.
I
2
C interface is a bi-directional serial bus that uses a serial data line (SDA) and a serial clock line
(SCL) for data transfer. The timing diagram for data transfer of this interface is given in Figure 1.
Data are transmitted synchronously to SCL clock on the SDA line on a byte-by-byte basis. Each
bit in a byte is sampled during SCL high with MSB bit being transmitted firstly. Each transferred
byte is followed by an acknowledge bit from receiver to pull the SDA low. The transfer rate of
this interface can be up to 400 kbps.
Figure 1 Data Transfer for I
2
C Interface
A master controller initiates the transmission by sending a “start” signal, which is defined as a
high-to-low transition at SDA while SCL is high. The first byte transferred is the slave address. It
is a seven-bit chip address followed by a RW bit. The chip address must be 001000x, where x
equals AD0. The RW bit indicates the slave data transfer direction. Once an acknowledge bit is
received, the data transfer starts to proceed on a byte-by-byte basis in the direction specified by
the RW bit. The master can terminate the communication by generating a “stop” signal, which is
defined as a low-to-high transition at SDA while SCL is high.
