General description
The TDA18272HN is a Silicon Tuner designed for terrestrial and cable TV reception for both analog and digital signals. TDA18272HN/M (Master) is to be used as a stand-alone tuner IC or Master in dual tuner application. TDA18272HN/S (Slave) is only to be used as Slave Silicon Tuner in dual tuner application.
The TDA18272HN supports all analog and digital TV standards and delivers a LOW IF (LIF) signal to a demodulator for analog TV and/or a channel demodulator for digital TV.
