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. A digital quadrature modulator with independent, frequency flexible NCOs are available to support multi-band operation. An optional low-jitter PLL/VCO simplifies the DAC sampling clock generation by allowing use of a lower frequency reference clock.

Power Supply Reference Design for Optimizing Spur and Phase Noise in RF-sampling DACs
TIDA-01215 — This reference design provides an efficient power supply scheme to power-up the RF-sampling DAC38RF8x digital-to-analog data converter (DAC) without sacrificing performance and also reduces board area and BOM. The reference design uses both DC/DC switchers and an LDO to power-up the DAC38RF8x while (...)
