Product data sheet

1. General description

The TDA18271HD is a Silicon Tuner IC designed mainly for terrestrial analog and digital

TV reception. The TDA18271HD integrates the overall tuning function, including

selectivity.

The TDA18271HD is compatible with all analog and digital TV standards and delivers a

low IF signal to a demodulator (for analog TV) and/or channel decoder (for digital TV).

This specification is based on software version 3.4.

2. Features

I Fully integrated RF tracking filters for unwanted signal suppression
