DAISY-CHAIN MODE
The AD1934 also allows a daisy-chain configuration to expand
the system 16 DACs (see Figure 12). In this mode, the DBCLK
frequency is 512 fS. The first eight slots of the DAC TDM data
stream belong to the first AD1934 in the chain and the last eight
slots belong to the second AD1934. The second AD1934 is the
device attached to the DSP TDM port.
To accommodate 16 channels at a 96 kHz sample rate, the
AD1934 can be configured into a dual-line, DAC TDM mode,
as shown in Figure 13. This mode allows a slower DBCLK than
normally required by the one-line TDM mode.
Again, the first four channels of each TDM input belong to the
first AD1934 in the chain and the last four channels belong to
the second AD1934.
The dual-line, DAC TDM mode can also be used to send data at
a 192 kHz sample rate into the AD1934, as shown in Figure 14.
The I/O pins of the serial ports are defined according to the
serial mode selected. See Table 13 for a detailed description of
the function of each pin. See Figure 18 for a typical AD1934
configuration with two external stereo DACs. Figure 15 and
Figure 16 show the serial mode formats. For maximum
flexibility, the polarity of LRCLK and BCLK are programmable.
In these figures, all of the clocks are shown with their normal
polarity. The default mode is I2S.
