10.3 Input data
It is recommended that the following additional settings are used to obtain optimum
performance at up to 750 Msps.
Table 31.
The setting applied to MODE_SEL (register 00h[3]; see
whether the DAC1405D750 operates in the Dual-port mode or in Interleaved mode (see
Table
Table 32.
The data input for Dual-port mode operation is shown in
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.
