Command & data handling (C&DH)

Block diagram

Overview

Our integrated circuits and reference designs help you create command and data handling (C&DH) systems complete with schematics, test data and design files.

Design requirements

    Modern C&DH designs require:

  • Highly integrated, point-of-load (POL) solutions for the space market that reduce overall board size required for even the highest power processing boards.
  • Rad-hard POL converter and low dropout (LDO) linear regulator components that drive optimal efficiency, size and power.
  • Integrated, high efficiency solutions for powering memory storage banks.
