Product Summary
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.
