TDM MODES
The AD1974 serial ports also have several different TDM serial
data modes. The first and most commonly used configuration
is shown in Figure 6 where the ADC serial port outputs one
data stream consisting of four on-chip ADCs followed by four
unused slots. In this mode, ABCLK is set to 256 fS (8-channel
TDM mode).
The I/O pins of the serial ports are defined according to the
serial mode selected. For a detailed description of the function
of each pin in TDM and AUX Modes, see Table 12.
The AD1974 allows system configurations with more than four
ADC channels (see Figure 7 and Figure 8) that use 8 ADCs and
16 ADCs. In this mode, four AUX channel slots in the TDM out-
put stream follow four on-chip ADC channel slots. It should be
noted that due to the high ABCLK frequency, this mode is
available only in the 48 kHz/44.1 kHz/32 kHz sample rate.
