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.
