8 mm Pitch, 144- Balls 3 Description 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...
