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 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.
