MAX5893 12-Bit/ 500Msps Interpolating and Modulating Dual DAC with CMOS Inputs

The MAX5893 programmable interpolating, modulating, 500Msps, dual digital-to-analog converter (DAC) offers superior dynamic performance and is optimized for highperformance wideband, single-carrier transmit applications. The device integrates a selectable 2x/4x/8x interpolating filter, a digital quadrature modulator, and dual 12-bit high-speed DACs on a sing.

Features

a fIM/4 digital image-reject modulator. This modulator generates a quadrature-modulated IF signal that can be presented to an analog I/Q modulator to complete the upconversion process. A second digital modulation mode allows the signal to be frequency-translated with image pairs at fIM/2 or fIM/4. The MAX5893 features a standard 1.8V CMOS, 3.3V tolerant data input bus for easy interface. A 3.3V SPI™ port is provided for mode configuration. The programmable modes include the selection of 2x/4x/8x interpolating filters, fIM/2, fIM/4 or no digital quadrature modulation with image rejection, chann.
