General Description
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 fIM / 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
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 pro-
grammable modes include the selection of 2x/4x/8x
interpolating filters, fIM / 2, fIM / 4 or no digital quadra-
ture 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.
