The MAX5895 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 IC. At 30MHz output frequency and 500Msps update rate, the in-band SFDR is 88dBc while consuming 1.1W. 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. 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 MAX5895 features a f_IM/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 f_IM/2 or f_IM/4.

The MAX5895 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, f_IM/2, f_IM/4 or no digital quadrature modulation with image rejection, channel gain and offset adjustment, and offset binary or two's complement data interface.

Pin-compatible 12- and 14-bit devices are also available. Refer to the MAX5894 data sheet for the 14-bit version and the MAX5893 data sheet for the 12-bit version.

Product Details

The MAX5893/MAX5894/MAX5895 evaluation kits (EV kits) are fully assembled and tested circuit boards that contain all the components necessary to evaluate the performance of this family of interpolating and modulating dual digital-to-analog converters (DACs). The EV kit boards include circuitry that converts the DAC differential output currents to single-ended voltages. The EV kits also include 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 MAX5893/MAX5894/MAX5895 through the use of an SPI™ interface.

The MAX5893/MAX5894/MAX5895 EV kits provide a proven PC board layout to facilitate evaluation of the MAX5893/MAX5894/MAX5895. The EV kits must be interfaced to appropriate timing signals for proper operation. When using the EV kits 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). Refer to the MAX5895 data sheet for timing requirements.

The MAX5895 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 for setup and operating instructions.

Order the complete EV system for comprehensive evaluation of the MAX5893/MAX5894/MAX5895 using a personal computer. Order the EV kit if the command module has already been purchased with another Maxim EV system, or for custom use in other microcontroller (µC)-based systems.

The MAX5893/MAX5894/MAX5895 EV kits can be used to evaluate the MAX5893 (12-bit), MAX5894 (14-bit), and the MAX5895 (16-bit) digital-to-analog converters. See the Ordering Information table for instructions on how to order the EV kit (and EV system) with these devices preinstalled.
