The MAX19692 12-bit, 2.3Gsps multiplexed digital-to-analog converter (DAC) enables digital synthesis of high-frequency and wideband signals in baseband and higher Nyquist zones. It has been optimized for wideband communications and radar applications. It has excellent spurious and noise performance and can be used for synthesis of wideband signals in the frequency range from DC to more than 2GHz. The 2.3Gsps update rate allows digital generation of signals with more than 1GHz bandwidth. The device synthesizes signals with excellent gain flatness and high SNR in the first three Nyquist zones directly, reducing the number of upconversion stages needed in a radio transmitter. With its unique ability to generate broadband signals over a wide frequency range, the MAX19692 enables ultra-high data rate wireless modems and multistandard software radio transmitters.
The MAX19692 features an update rate up to 2.3Gsps, and has four 12-bit multiplexed low-voltage differential signaling (LVDS) input ports that operate up to 575MHz. The device accepts a clock at the DAC update rate that can be either a sine wave or a square wave. The input data rate is 1/4 the DAC update rate. The MAX19692 provides an LVDS data clock output to simplify interfacing to FPGA or ASIC devices.
The MAX19692 is a current-steering DAC with an integrated, self-calibrated 50Ω differential output termination to ensure optimum dynamic performance. The MAX19692 operates from 3.3V and 1.8V power supplies and consumes 760mW at 1.0Gsps.
