The MAX19693 12-bit, 4.0Gsps digital-to-analog converter (DAC) enables direct digital synthesis of high-frequency and wideband signals. The DAC has been optimized for wideband communications and radar applications. The MAX19693 provides excellent spurious and noise performance and can be used for synthesis of wideband signals in the frequency range from DC to nearly 2GHz. The 4.0Gsps update rate enables digital synthesis of signals with more than 1.5GHz bandwidth.
The MAX19693 includes four 12-bit multiplexed low-voltage differential signaling (LVDS) input ports, each operating at up to 1GHz in double data rate (DDR) or quad data rate (QDR) mode. The DAC accepts a clock at 1/2 the DAC update rate, as conversion is triggered on both rising and falling clock edges. The input data rate is 1/4 the DAC update rate (1/2 the clock rate). The MAX19693 provides an LVDS data clock output to simplify interfacing to FPGA or ASIC devices.
The MAX19693 is a current-steering DAC with an integrated, self-calibrated 50Ω differential output termination to ensure optimum dynamic performance. The MAX19693 operates from 3.3V and 1.8V power supplies and consumes 1180mW at 4.0Gsps. The MAX19693 is specified over the extended temperature range (-40°C to +85°C) and is available in a compact 11mm x 11mm, 169 CSBGA package.
