ADDITIONAL MODES
The AD1938 offers several additional modes for board level
design enhancements. To reduce the EMI in board level design,
serial data can be transmitted without an explicit BCLK. See
Figure 27 for an example of a DAC TDM data transmission
mode that does not require high speed DBCLK. This configu-
ration is applicable when the AD1938 master clock is generated
by the PLL with the DLRCLK as the PLL reference frequency.
To relax the requirement for the setup time of the AD1938 in
cases of high speed TDM data transmission, the AD1938 can
latch in the data using the falling edge of DBCLK. This effectively
dedicates the entire BCLK period to the setup time. This mode
is useful in cases where the source has a large delay time in the
serial data driver. Figure 28 shows this pipeline mode of data
transmission.
Both the BLCK-less and pipeline modes are available on the
ADC serial data port.
