DAC1401D125
Dual 14-bit DAC, up to 125 Msps
In Interleaved mode, both DACs use the same data and clock inputs at twice the update
rate. Data enters the latch on the rising edge of IQWRT. The data is sent to either latch A
or latch B, depending on the value of IQSEL. The IQSEL transition must occur when
IQWRT and IQCLK are LOW.
The IQCLK is divided by 2 internally and the data is transferred to the DAC latch. It is
updated on its rising edge. When IQRESET is HIGH, IQCLK is disabled, see
Figure 17
