A high dynamic range allows the DAC38RFxx family to generate 3G/4G signals for wireless basestations with an output frequency up to 4 GHz. The devices feature a low-power JESD204B Interface with up to 8 lanes, and provides a maximum bit rate of 12.5 Gbps and input sample rate of 1.25 GSPS complex per channel. The DAC38RFxx provides two digital upconverters per DAC, with multiple interpolation rates and a digital quadrature modulator with independent, frequency flexible NCOs. An optional low-jitter PLL/VCO simplifies the DAC clock generation by allowing use of a lower frequency reference clock.
