16-BIT, 1.0 GSPS 2x-4x INTERPOLATING DUAL-CHANNEL DIGITAL-TO-ANALOG CONVERTER (DAC)

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 -40C to 85C and is available in a 64-pin QFN package. Other single-channel members of the family include the interpolating DAC5681Z and non-interpolating DAC5681.
