10.3 Input data
The setting applied to MODE_SEL (register 00h[3]; see
Table 10 on page 17
) and it
defines whether the DAC1405D650 operates in the Dual-port mode or in the Interleaved
mode (see
Table 30
).

10.3.1
Dual-port mode
The data input for Dual-port mode operation is shown in
Figure 5 “Dual-port mode”
. Each
DAC has its own independent data input. The data enters the input latch on the rising
edge of the internal clock signal and is transferred to the DAC latch.
10.3.2
Interleaved mode
The data input for the Interleaved mode operation is illustrated by
Figure 6 “Interleaved
mode operation”
.
