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

[1] The maximum allowed ambient temperature Tamb(max) depends on the assembly conditions of the package and especially on the design
of the Printed-Circuit Board (PCB) and die connection. The application mounting must be done in such a way that the maximum junction
temperature is never exceeded. The junction temperature can be obtained by reading the temperature sensor bit via I2C-bus. The
junction temperature: Tj = Tamb + ΔTj-c. where ΔTj-c = power × Rth.
[2] Class III: 500 V to 1000 V.
