The MAX5893 programmable interpolating, modulating, 500Msps, dual digital-to-analog converter (DAC) offers superior dynamic performance and is optimized for high- performance wideband, single-carrier transmit applica- tions. The device integrates a selectable 2x/4x/8x nterpolating filter, a digital quadrature modulator, and dual 12-bit high-speed DACs on a single integrated cir- cuit. At 30MHz output frequency and 500Msps update rate, the in-band SFDR is 84dBc while consuming 1.1W. The device also delivers 72dB ACLR for single-carrier WCDMA at a 61.44MHz output frequency. The selectable interpolating filters allow lower input data rates while taking advantage of the high DAC update rates. These linear-phase interpolation filters ease reconstruction filter requirements and enhance the passband dynamic performance. Individual offset and gain programmability allow the user to calibrate out local oscillator (LO) feedthrough and sideband suppression errors generated by analog quadrature modulators.
