14-Bit, 500Msps, Interpolating and Modulating

Dual DAC with CMOS Inputs

General Description

Features

= 61.44MHz (Single-Carrier

OUT

The MAX5894 programmable interpolating, modulating,

500Msps, dual digital-to-analog converter (DAC) offers

superior dynamic performance and is optimized for high-

performance wideband, single-carrier transmit applica-

tions. The device integrates a selectable 2x/4x/8x

interpolating filter, a digital quadrature modulator, and

dual 14-bit, high-speed DACs on a single integrated cir-

cuit. At 30MHz output frequency and 500Msps update

rate, the in-band SFDR is 86dBc while consuming 1.1W.

The device also delivers 73dB ACLR for two-carrier

WCDMA at a 61.44MHz output frequency.

♦ 74dB ACLR at f

WCDMA)

♦ Meets 3G UMTS, cdma2000^®, GSM Spectral Masks

(f = 122MHz)

OUT

♦ Noise Spectral Density = -154dBFS/Hz at

= 16MHz

OUT

♦ 91dBc SFDR at Low-IF Frequency (10MHz)

♦ 88dBc SFDR at High-IF Frequency (50MHz)

♦ Low Power: 886mW (f

= 250MHz)

CLK

♦ User Programmable

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.
