  • Includes major chips plus hundreds of passives on one piece of silicon

  • Single power supply

  • 18-25% lower RBOM

  • Not a complete system-on-a-chip

  • Needs extra power supplies

  • Increased BOM for external line driver

  • Multi-chip module – a single package but not one piece of silicon

  • Multiple power supplies required
