TDA8275HN  -Silicon Tuner Family

The TDA827x silicon tuner family offers a very simple tuner solution for 

cable modem, digital STB and analog PC-TV reception, enabling incredible 

simplifications in TV design. Its patented technology and highly innovative 

architecture reduces external component count, providing an extremely 

cost effective silicon tuner that is easier and quicker to design in than any 

other comparable solution in today’s market.

A giant leap forward in RF integration, the TDA827x features an embedded 

low noise input amplifier and an image rejection mixer for processing RF 

signals and downconverting to low IF signals, which are then filtered before 

being sent to the channel decoder or IF demodulator. It offers optimal 

partitioning of functions at the system level, removing the need for both 

SAW filters or IF amplifiers. 

This family also features a fully integrated VCO that has no external tank 

component, an RF splitter with two separate outputs and an RSSI signal 

indicator embedded on the IC. All this integration results in very low power 

consumption for the TDA827x, removing the need for an external heat sink 

and further simplifying design-in efforts.
