Dual-port mode
The data and clock circuit for Dual-port mode operation is shown in
Figure 14
.
Each DAC has its own independent data and clock inputs. The data enters the input latch
on the rising edge of the WRTA/WRTB signal and is transferred to the DAC latch. The
output is updated on the rising edge of the CLKA/CLKB signal.
