DAC5681Z 说明
The DAC5681Z is a 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 DAC5681Z offers superior linearity, noise, crosstalk and PLL phase noise performance.
The DAC5681Z 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.
