TDA827x

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.
