Oscilloscopes & digitizers

Block diagram

Overview

High-speed digitizers, low-noise clocking, high-speed signal chain and low-noise power are critical elements of high-performance oscilloscopes & digitizers. Our integrated circuits and reference designs help you design high-speed and high-resolution next generation oscilloscopes.

Design requirements

High-performing oscilloscopes & digitizers designs often require:

  • Digitizers that can be interleaved on-chip or on-board to achieve higher sampling rates.
  • Ultra-low noise clocking help to achieve low skew and high horizontal resolution.
  • Low noise and low EMI power supplies to enable high system ENOB.
