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

Features and benefits

  • Fully integrated IF selectivity; eliminating the need for external SAW filters
  • Fully integrated oscillators with no external components
  • Integrated wideband gain control
  • Alignment free
  • RF loop-through for easy implementation in the Set-Top Box (STB)
  • Integrated die thermal sensor
  • Single 3.3 V power supply
  • Low power consumption (750 mW)
  • Crystal oscillator output buffer (16 MHz) for single crystal applications
  • I²C-bus interface compatible with 3.3 V and 5 V microcontrollers
  • Three Standby modes
  • RoHS packaging

Applications

  • DVB-T Set-Top Box (STB) and TV receiver
  • System application optimization is described in the application note AN0814
  • Driver application is described in the application note AN0822
