AUDIO PORT MODES
The SRC4192 and SRC4193 both support seven serial port
modes, which are shown in Table 1. For the SRC4192, the
audio port mode is selected using the MODE0 (pin 26),
MODE1 (pin 27), and MODE2 (pin 28) inputs. For the
SRC4193, the mode is selected using the MODE[2:0] bits in
Control Register 1. The default mode setting for the SRC4193
is both input and output ports set to Slave mode.
In Slave mode, the port LRCK and BCK clocks are config-
ured as inputs, and receive their clocks from an external
audio device. In Master mode, the LRCK and BCK clocks are
configured as outputs, being derived from the reference
clock input (RCKI). Only one port can be set to Master mode
at any given time, as indicated in Table 1.
INPUT PORT OPERATION
The audio input port is a three-wire synchronous serial
interface that may operate in either Slave or Master mode.
The SDIN input (pin 4) is the serial audio data input. Audio
data is input at this pin in one of three standard audio data
formats: Philips I
2
S, Left Justified, or Right Justified. The
audio data word length may be up to 24-bits for I
2
S and Left
Justified formats, while the Right Justified format supports
16-, 18-, 20-, or 24-bit data. The data formats are shown in
Figure 4, while critical timing parameters are shown in Figure
5 and listed in the Electrical Characteristics table.
