General description
The TDA18211HD is a Silicon Tuner IC designed for digital terrestrial (DVB-T) TV reception. The TDA18211HD integrates the overall tuning function, including selectivity, and provides a low-IF output signal. The TDA18211HD uses integrated IF filters to support 6/7/8 MHz channel bandwidths. The TDA18211HD requires only one single 16 MHz crystal for clock generation. A clock signal is available on crystal oscillator output pins (XTOUTP/XTOUTN) to synchronize the channel decoder and slave front end in case of DVR configuration.

FEATUREs
■ Fully integrated RF tracking filters for unwanted signal suppression
