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

Overview

TopologyOther Topology
IC revisionE1

Description

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

  • Sampling rate up to 12.8GSPS, using timeinterleaved 12-bit RF-sampling ADCs
  • Analog front end support up to 6-GHz bandwidth
  • Fine sample clock phase adjustment (19 fs resolution)
  • Phase synchronization of multiple ADCs
  • Companion power reference design with a >85% efficiency at 12-V input
  • JESD204B supporting 8, 16, or 32 JESD lanes, data rates up to 12.8 Gbps per lane

Typical applications

  • Test and Measurement / Industrial Instrumentation
