General Description
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 modula-
tor, 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 fIM/4 digital image-reject mod-
ulator. This modulator generates a quadrature-modulat-
ed 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 MAX5895 features a standard 1.8V CMOS, 3.3V tol-
erant 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 fil-
ters, fIM/2, fIM/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.
