DAC5686

SLWS147B – APRIL 2003 – REVISED AUGUST 2004

In dual-bus mode, two separate parallel data streams (I and Q) are input to the DAC5686 on data bus DA and

data bus DB. Dual-bus mode is selected by setting INTERL to 0 in the config_msb register. Figure 28 shows

the DAC5686 data path in dual-bus mode. The dual-bus mode timing diagram is shown in Figure 29 for the PLL

clock mode and in Figure 30 for the external clock mode.
