interpolating
In the 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 de-multiplexed I and
Q channels; see
Figure 7 “Interleaved mode timing (8x interpolation, latch on rising
edge)”
.
SELIQ can be either a synchronous or asynchronous (single rising edge, single pulse)
signal. The first data following the SELIQ rising edge will be sent in channel I and following
data will be sent in channel Q. After this, data will be distributed alternately between these
channels.
