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 50 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.
