The DAC38RFxx isa family of high-performance, dual/single-channel, 14-bit, 9-GSPS,RF-sampling digital-to-analog converters (DACs) that are capable of synthesizing wideband signalsfrom 0 to 4.5 GHz. A high dynamic range allows the DAC38RFxxfamily to generate signals for a wide range of applications including 3G/4G signals for wirelessbase-stations and radar.
The devices feature a low-power JESD204B Interface with up to 8 lanes with a maximum bitrate of 12.5 Gbps allowing an input data rate of 1.25 GSPS complex per channel. The DAC38RFxxprovides two digital up-converters per channel, with multiple options for interpolation rates. Adigital quadrature modulator with independent, frequency flexible NCOs are available to supportmulti-band operation. An optional low-jitter PLL/VCO simplifies the DACsampling clock generation by allowing use of a lower frequency reference clock.
