DAC1405D750
Dual 14-bit DAC, up to 750 Msps; 4
and 8
interpolating
In Interleaved mode, both DACs use the same data input at twice the Dual-port mode
frequency. Data enters the latch on the rising edge of the internal clock signal. The data is
sent to either latch I or latch Q, depending on the SELIQ signal.
The SELIQ input (pin 41) allows the synchronization of the internally demultiplexed I and
Q channels; see
Figure 7
.
The SELIQ signal can be either synchronous or asynchronous (single rising edge, single
pulse). The first data following the SELIQ rising edge is sent in channel I and following
data is sent in channel Q. After this, data is distributed alternately between these
channels.
