Thedigital interface consists of two double-buffered latches as well as control logic. Separate write inputs allow data to be written to the two DAC ports independent of one another. Separate clocks control the update rate of the DACs.A mode control pin allows the AD9763/AD9765/AD9767 to interface to two separate data ports, or to a single interleavedhigh speed data port. In interleaving mode, the input datastream is demuxed into its original I and Q data and then latched.
