General Description

Features

o 71dB ACLR at f

= 61.44MHz (Four-Carrier

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 cir-

cuit. 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 recon-

struction 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 suppres-

sion errors generated by analog quadrature modulators.

The MAX5898 features a f / 4 digital image-reject

modulator. This modulator generates a quadrature-mod-

ulated 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

data is applied through a single 16-bit bus. A 3.3V

SPI™ port is provided for mode configuration. The pro-
