Texas Instruments DAC38RF84
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. 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.| Part No. | DAC38RF84 |
