20-Bit, 1-MSPS Isolated Data Acquisition Reference Design Optimizing Jitter for Maximum SNR and Sample Rate

Overview

TopologyOther Topology

Description

The TIDA-01035 is a 20-bit, 1 MSPS isolated analog input data acquisition reference design demonstrating how to resolve and optimize performance challenges typical of digitally isolated data acquisition systems.Significantly improves high frequency AC signal chain performance (SNR and THD) by effectively mitigating ADC sample clock jitter across isolation boundaryMaximizes sample rate by eliminating/minimizing propagation delay introduced by a digital isolatorProvides option to evaluate performance with and without jitter mitigation technique with jumperIncludes detailed timing analysis detailing the isolator’s additive jitter impact on data throughput

Features

Isolated 20-Bit, 1-MSPS, Single-ChannelDifferential Input Data Acquisition (DAQ) System

  • Jitter Mitigation Technique Realizes More Than 18-dB System-Level SNR Improvement for High-Frequency Input Signals (100-kHz Fin, 1 MSPS)
  • Reduced Logic (on Isolated ADC Side) EliminatesNeed for Higher Power and Complex PLL Solutions
  • Achieves 1-MSPS Sampling Rate While PreservingLow SPI CLK Rates With the ADS8900B ADC’sInnovative multiSPI™ and ADC Master or Source-Synchronous Mode Digital Interfaces
