NXP TDA18218HN Data Sheet
Update: 30 September, 2023
TDA18218HN is a Silicon Tuner IC designed for digital terrestrial (DVB-T) TV reception. TDA18218HN integrates the overall tuning function, including selectivity and provides a low-IF output signal. TDA18218HN uses integrated IF filters to support 6 MHz, 7 MHz or 8 MHz channel bandwidths. 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. TDA18218HN is a low cost Silicon Tuner targeting digital terrestrial applications. 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 2. Features I Fully integrated IF selectivity; eliminating the need for external SAW filters I Fully integrated oscillators with no external components I Integrated wideband gain control I Alignment free I RF loop-through for easy implementation in the Set-Top Box (STB) I Integrated die thermal sensor I Single 3.3 V power supply I Low power consumption (750 mW) I Crystal oscillator output buffer (16 MHz) for single crystal applications I I2C-bus interface compatible with 3.3 V and 5 V microcontrollers I Three Standby modes I RoHS packaging 3. Applications I DVB-T Set-Top Box (STB) and TV receiver I System application optimization is done
