19-3546; Rev 1; 4/07 EVALUATION KIT AVAILABLE 12-Bit, 500Msps Interpolating and Modulating Dual DAC with CMOS Inputs MAX5893 General Description Features The MAX5893 programmable interpolating, modulating, 72dB ACLR at fOUT = 61.44MHz (Single-Carrier 500Msps, dual digital-to-analog converter (DAC) offers WCDMA) superior dynamic performance and is optimized for high- Meets 3G UMTS, cdma2000®, GSM Spectral Masks performance wideband, single-carrier transmit applica- (fOUT = 122MHz) tions. The device integrates a selectable 2x/4x/8xinterpolating filter, a digital quadrature modulator, and Noise Spectral Density = -151dBFS/Hz at dual 12-bit high-speed DACs on a single integrated cir- fOUT = 16MHz cuit. At 30MHz output frequency and 500Msps update 90dBc SFDR at Low-IF Frequency (10MHz) rate, the in-band SFDR is 84dBc while consuming 1.1W. 86dBc SFDR at High-IF Frequency (50MHz) The device also delivers 72dB ACLR for single-carrierWCDMA at a 61.44MHz output frequency. Low Power: 511mW (fCLK = 100MHz) The selectable interpolating filters allow lower input data User Programmable rates while taking advantage of the high DAC update Selectable 2x, 4x, or 8x Interpolating Filters rates. These linear-phase interpolation filters ease <0.01dB Passband Ripple reconstruction filter requirements and enhance the >99dB Stopband Rejection passband dynamic performance. Individual offset and Selectable Real or Complex Modulator Operation gain programmability allow the user to calibrate out local Selectable Modulator LO Frequency: OFF, fIM / 2, oscillator (LO) feedthrough and sideband suppression or fIM / 4 errors generated by analog quadrature modulators. Selectable Output Filter: Lowpass or HighpassChannel Gain and Offset Adjustment The MAX5893 features a fIM / 4 digital image-rejectmodulator. This modulator generates a quadrature-mod- EV Kit Available (Order the MAX5893EVKIT) ulated IF signal that can be presented to an analog I/Q Ordering Information modulator to complete the upconversion process. Asecond digital modulation mode allows the signal to be PIN- PKG PART TEMP RANGE frequency-translated with image pairs at fIM / 2 or fIM / 4. PACKAGE CODE The MAX5893 features a standard 1.8V CMOS, 3.3V tol-
