Product Description
Figure 1 - Functional Block Diagram
The RDA012M4MS is a digital-to-analog
converter (DAC) with a 4:1 input multiplexer and
a maximum update rate of 1.3GS/s. The
RDA012M4MS features master-slave operation
that simplifies synchronization when multiple
devices are required, such as in an I-Q
modulation scheme. The integrated DAC utilizes
a segmented current source to reduce the glitch
energy and achieve high linearity performance.
For best dynamic performance, the DAC outputs
are internally terminated with 50Ω resistance,
and outputs a nominal full-scale current of 12mA
when terminated with external 50Ω resistors. For
a convenient interface with most CMOS ICs, the
digital data inputs are low voltage NMOS
compatible.
