ST’s solid-state silicon TV tuners have recently been developed to replace traditional CAN tuners, a venerable technology little changed since the late 1960's and made up of numerous discrete components that required careful and time-consuming tuning.
Silicon tuners offer the following advantages as compared to CAN tuners:
Overall cost reduction compared to CAN tuners
No manual tuning or adjustments
Set-top box or TV form factor reduction; smaller footprint
