TDA18212HN
Silicon Tuner for terrestrial and cable digital TV reception
Rev. 2 — 12 August 2010
Product data sheet
1. General description
The TDA18212HN is a Silicon Tuner designed for terrestrial and cable TV reception for
digital signals. TDA18212HN/M (Master) is to be used as a stand-alone tuner IC or Master
in dual tuner application. TDA18212HN/S (Slave) is only to be used as Slave Silicon
Tuner in dual tuner application.
The TDA18212HN supports all digital TV standards and delivers a LOW IF (LIF) signal to
a channel demodulator for digital TV.
The TDA18212HN facilitates design-ins by:
• Allowing easy on-board integration
• Drastically reducing the size of the tuner function
• Providing flexibility in system solution development
• Allowing straightforward dual tuner applications optimization

[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.
