●The DAC5682Z is a dual-channel 16-bit 1.0 GSPS DAC with wideband LVDS data input, integrated 2x/4x interpolation filters, onboard 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 onboard 2x or 4x FIR filters. Each interpolation FIR is configurable in either 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 both complex or real output. An optional Fs/4 coarse mixer in complex mode provides coarse frequency upconversion and the dual DAC output produces a complex Hilbert Transform pair. An external RF quadrature modulator then performs the final single sideband up-conversion. The interpolation filters and complex coarse mixers efficiently provide frequency plan flexibility while enabling higher output DAC rates to simplify image rejection filtering.
●The DAC5682Z is characterized for operation over the industrial temperature range of 40°C to 85°C and is available in a 64-pin QFN package. Other single-channel members of the family include the interpolating DAC5681Z and the noninterpolating DAC5681.
