The MAX5898 programmable interpolating, modulating, 500Msps, dual digital-to-analog converter (DAC) offers superior dynamic performance and is optimized for high-performance wideband, single- and multicarrier transmit applications. The device integrates a selectable 2x/4x/8x interpolating filter, a digital quadrature modulator, and dual 16-bit, high-speed DACs on a single integrated circuit. At 30MHz output frequency and 500Msps update rate, the in-band SFDR is 81dBc, while only consuming 1.2W. The device also delivers 71dB ACLR for four-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. Each channel includes offset and gain programmability, allowing the user to calibrate out local oscillator (LO) feedthrough and sideband suppression errors generated by analog quadrature modulators.
The MAX5898 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 MAX5898 features a standard LVDS interface for low electromagnetic interference (EMI). Interleaved data is applied through a single 16-bit bus. 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, individual channel gain and offset adjustment, and offset binary or two's-complement data interface.
Compatible versions with CMOS interfaces and 12-, 14-, and 16-bit resolutions are also available. Refer to the MAX5893 data sheet for 12-bit CMOS, MAX5894 for 14-bit CMOS, and the MAX5895 for 16-bit CMOS versions.
See a parametric table of the complete family of pin-compatible, 12-/14-/16-bit high-speed DACs.

MAX5898EVCMOD2
Evaluation System/Evaluation Kit for the MAX5898
Product Detail
The MAX5898 evaluation kit (EV kit) is a fully assembled and tested circuit board that contains all the components necessary to evaluate the performance of the MAX5898 interpolating and modulating dual digital-to-analog converter (DAC). The EV kit board includes circuitry that converts the DAC differential output currents to single-ended voltages. The EV kit also includes circuitry that generates a clock signal from an AC sine-wave input signal.
The included evaluation software runs under Windows® 98/2000/XP, providing a graphical user interface (GUI) to exercise the features of the MAX5898 through the use of an SPI® interface.
The MAX5898 EV kit provides a proven PC board layout to facilitate evaluation of the MAX5898. The EV kit must be interfaced to appropriate timing signals for proper operation. When using the EV kit without the CMOD232 command module, connect the system-side power (VMOD), ground-return (GND), and interface (SCLK, CS, DIN, DOUT) signals to the pads on the PC board (see Figure 5 in the full data sheet). Refer to the MAX5898 data sheet for timing requirements.
The MAX5898 evaluation software runs under Windows 98/2000/XP on an IBM® PC, interfacing to the EV system board (CMOD232) through the computer's serial communications port. See the Quick Start section in the full data sheet for setup and operating instructions.
Order the complete EV system (MAX5898EVCMOD2) for comprehensive evaluation of the MAX5898 using a personal computer. Order the EV kit (MAX5898EVKIT) if the command module has already been purchased with another Maxim EV system, or for custom use in other microcontroller (µC)-based systems.
