The DAC5682ZIRGCT is a 2-channel 16-bit Digital-to-analog Converter (DAC) with wideband LVDS data input, integrated 2x/4x interpolation filters, on board clock multiplier and internal voltage reference. The DAC5682Z offers superior linearity, noise, crosstalk and PLL phase noise performance. The DAC5682Z integrates a wideband LVDS port with on-chip termination. Full-rate input data can be transferred to a single DAC channel or half-rate and 1/4-rate input data can be interpolated by on board 2x or 4x FIR filters. Each interpolation FIR is configurable in low-pass or high-pass mode, allowing selection of a higher order output spectral image. An on-chip delay lock loop (DLL) simplifies LVDS interfacing by providing skew control for the LVDS input data clock. The DAC5682Z allows complex or real output. An optional Fs/4 coarse mixer in complex mode provides coarse frequency up-conversion and the dual DAC output produces a complex Hilbert Transform pair.
