General description
The TDA18218HN is a Silicon Tuner IC designed for digital terrestrial (DVB-T) TV reception. The TDA18218HN integrates the overall tuning function, including selectivity and provides a low-IF output signal.
The TDA18218HN uses integrated IF filters to support 6 MHz, 7 MHz or 8 MHz channel bandwidths. The TDA18218HN requires only one single 16 MHz crystal for clock generation. A clock signal is available on crystal oscillator output pins (XTO_P / XTO_N) to synchronize the channel decoder.

The TDA18218HN is a low cost Silicon Tuner targeting digital terrestrial applications. The TDA18218HN matches the performance of the conventional can tuners. Additionally, the following benefits can be stated:
• Easy on-board integration
• Drastically reduces:
– the size of the tuner function
– the power consumption
