Power Supply Reference Design for Optimizing Spur and Phase Noise in RF-sampling DACs
TIDA-01215
Overview
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 achieving high analog performance (spurious and phase noise) and minimizing power efficiency trade-offs. The design method outlined here can be extended to the power supply design of other RF-sampling data converters.
Features
- Provides an Efficient Power Solution for RF-Sampling DACs
- Enables Optimal Spur and Phase Noise Performance
- Reduces Board Area
- Lowers Bill of Materials (BOM) Cost
