TIDA-01027

Low noise power-supply reference design maximizing performance in 12.8 GSPS data acquisition systems

TIDA-01027

Design files

Overview

This reference design demonstrates an efficient, low noise 5-rail power-supply design for very high-speed DAQ systems capable of > 12.8 GSPS. The power supply DC/DC converters are frequency synchronized and phase-shifted in order to minimize input current ripple and control frequency content. Furthermore, any potential radiated electromagnetic interference (EMI) is minimized by using high performance HotRodTM packaging technology.

Features
  • Efficient, low-noise, point-of-load DAQ power supply for very high-speed AFE
  • Phase-shifting DC/DC converter clocks to reduce inrush current and power-supply noise
  • External frequency sync to manage DC/DC converters spurs
  • Configure output with ability to bypass each LDO and use just the DC/DC converter and filter
  • Used with TIDA-01022 and TIDA-01028 to show the impact on a 12.8 GSPS AFE with 9 GHz of analog BW

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
