Our integrated circuits and reference designs for professional video up/down/cross conversion include complete schematics, test data and design files.

Design requirements

Modern up/down/cross conversion designs often require:

  • Low-noise level conversion when moving video/audio between analog and digital formats.
  • Best-in-class performance in signal integrity, power and cable reach.
  • Easy-to-embed or de-embed audio to balanced analog or AES/EBU digital connections.
  • Flexibility to configure I/O with eye monitor providing system debug capability.
