TV TunersRipe for Innovation

• RF front end has resisted integration due to
  performance
• Previous attempts could not match the performance
  of traditional discrete tuners and hybrid iDTVs
  increase performance challenges
• To date, silicon tuners only successful in less
  strenuous set-top box and PC-TV applications,
  discrete tuners still used in iDTV for highest
  performance
• Catalysts for change include
• Transition from analog to hybrid
  createsadditional complexity and cost
• Continuous pressure to reduce system and
  manufacturing costs
• Slimmer TV form factors creating space
  constraints
