MAX5878 Datasheet | Maxim Integrated

19-3591; Rev 0; 2/05 KIT ATION EVALU E L B AVAILA .. 16-Bit, 250Msps, High-Dynamic-Performance, Dual DAC with LVDS Inputs General Description The MAX5878 is an advanced 16-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 76d Bc spurious-free dynamic range (SFDR) at f OUT = 16MHz and supports update rates of 250Msps, with a power dissipation of only 296m W. The MAX5878 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 MAX5878 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 MAX5878 is available in a 68-pin QFN package with an exposed paddle (EP) and is specified for the extended temperature range (-40°C to +85°C). Refer to the MAX5876- and MAX5877- data sheets for pin-patible 12-bit and 14-bit versions of the MAX5878, respectively. Refer to the MAX5875 data sheet for a CMOS-patible version of the MAX5878. - 250Msps Output Update Rate - Noise Spectral Density = -164d BFS/Hz at f OUT = 16MHz - Excellent SFDR and IMD SFDR = 76d Bc at f OUT = 16MHz (to Nyquist) SFDR = 71d Bc at f OUT = 80MHz (to Nyquist) IMD = -90d Bc at f OUT = 10MHz IMD = -72d Bc at f OUT = 80MHz - ACLR = 75d B at f OUT = 61MHz - 2m A to 20m A Full-Scale Output Current - LVDS-patible Digital and Clock Inputs - On-Chip...
