19-3632; Rev 0; 4/05 KIT ATION EVALU E L B AVAILA 14-Bit, 250Msps, High-Dynamic-Performance, Dual DAC with LVDS Inputs General Description The MAX5877 is an advanced 14-bit, 250Msps, dual digital-to-analog converter (DAC). This DAC meets the demanding performance requirements of signal synthesis applications found in wireless base stations and other munications applications. Operating from +3.3V and +1.8V supplies, this dual DAC offers exceptional dynamic performance such as 75d Bc spurious-free dynamic range (SFDR) at f OUT = 16MHz and supports update rates of 250Msps, with a power dissipation of only 287m W. The MAX5877 utilizes a current-steering architecture that supports a 2m A to 20m A full-scale output current range, and allows a 0.1VP-P to 1VP-P differential output voltage swing. The device Features an integrated +1.2V bandgap reference and control amplifier to ensure high-accuracy and low-noise performance. A separate reference input (REFIO) allows for the use of an external reference source for optimum flexibility and improved gain accuracy. The clock inputs of the MAX5877 accept both LVDS and LVPECL-patible voltage levels. The device Features an interleaved data input that allows a single LVDS bus to support both DACs. The MAX5877 is available in a 68-pin QFN package with an exposed pad (EP) and is specified for the extended temperature range (-40°C to +85°C). Refer to the MAX5876 and MAX5878 data sheets for pin-patible 12-bit and 16-bit versions of the MAX5877, respectively. Refer to the MAX5874 data sheet for a CMOS-patible version of the MAX5877. o 250Msps Output Update Rate o Noise Spectral Density = -160d BFS/Hz at f OUT = 16MHz o Excellent SFDR and IMD SFDR = 75d Bc at f OUT = 16MHz (to Nyquist) SFDR = 71d Bc at f OUT = 80MHz (to Nyquist) IMD = -87d Bc at f OUT = 10MHz IMD = -73d Bc at f OUT = 80MHz o ACLR = 75d B at f OUT = 61MHz o 2m A to 20m A Full-Scale Output Current o LVDS-patible Digital and Clock Inputs o On-Chip +1.20V Bandgap Reference o...
