TDA18272HN

Hybrid (analog and digital) Silicon Tuner for terrestrial and

cable TV reception

Rev. 2 — 11 August 2010

Product data sheet

1. 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.

2. Features and benefits
