The DAC38RFxx is
a family of high-performance, dual/single-channel, 14-bit, 9-GSPS,
RF-sampling digital-to-analog converters (DACs) that are capable of synthesizing wideband signals
from 0 to 4.5 GHz. A high dynamic range allows the DAC38RFxx
family to generate signals for a wide range of applications including 3G/4G signals for wireless
base-stations and radar.
The devices feature a low-power JESD204B Interface with up to 8 lanes with a maximum bit
rate of 12.5 Gbps allowing an input data rate of 1.25 GSPS complex per channel. The DAC38RFxx
provides two digital up-converters per channel, with multiple options for interpolation rates. A
digital quadrature modulator with independent, frequency flexible NCOs are available to support
multi-band operation. An optional low-jitter PLL/VCO simplifies the DAC
sampling clock generation by allowing use of a lower frequency reference clock.
