MAXIM MAX5893 12-Bit 500Msps Interpolating Modulating Dual DAC with CMOS Inputs handbook
Update: 28 September, 2023
The MAX5893 is a programmable interpolating, modulating, 500Msps, dual digital-to-analog converter (DAC) optimized for high-performance wideband, single-carrier transmit applications. It integrates a selectable 2x/4x/8x interpolating filter, a digital quadrature modulator, and dual 12-bit high-speed DACs on a single integrated circuit. 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. The MAX5893 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.
