The data is de-interleaved backinto its original I and Q data. An on-chip state machine ensures theproper pairing of I and Q data. The data output from each latch isthen processed by a 2x digital interpolation filter that eases thereconstruction filter requirements. The interpolated output of eachfilter serves as the input of their respective 10-bit DAC.The DACs utilize a segmented current source architecture combinedwith a proprietary switching technique to reduce glitchenergy and to maximize dynamic accuracy. Each DAC providesdifferential current output thus supporting single-ended ordifferential applications. Both DACs are simultaneously updatedand provide a nominal full-scale current of 10 mA. Also,the full-scale currents between each DAC are matched to within0.07 dB (i.e., 0.75%), thus eliminating the need for additionalgain calibration circuitry.The AD9761 is manufactured on an advanced low cost CMOSprocess.
