DESCRIPTION
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.
