TDA827x

Based on a revolutionary concept, the TDA827x silicon tuner

family frees manufacturers from many of the constraints of

traditional RF design. This comprehensive silicon tuner family

for cable modem, digital STB and analog PC-TV reception

offers the necessary selectivity for all targeted applications.

Applications

• DOCSIS and EuroDOCSIS cable modems

• Digital Set Top Boxes

• Analog TV reception on PCs

Common features

• Real Silicon tuner approach: only 30 SMD components

• Wideband low noise RF amplifier with AGC

• Integrated and Programmable Selectivity

• RF splitter with 2 separate outputs (-2 / +6 dB)

• RF filter

• Image rejection mixer stage

• Fully integrated VCO

• RSSI signal indicator, +/- 0.5 dB relative accuracy

• Integrated 16 MHz crystal oscillator and output buffer

• I²C bus controlled

• Temperature range: -20 to + 70°C

• Power: 3.3V, 1.29 W (typical)

• Package: MLF 40 pins 6 x 6 mm HVQFN40

Silicon Tuner Family

S e m i c o n d u c t o r s

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.
