Description

The DAC5682Z is a dual-channel 16-bit 1.0 GSPS 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 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 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 non-interpolating DAC5681.
