TDA18273HN
Hybrid (analog and digital) Silicon Tuner for terrestrial and
cable TV reception
Rev. 3 — 10 May 2011
Product short data sheet
1. General description
The TDA18273HN is a high performance Silicon Tuner designed for terrestrial and cable
TV reception for both analog and digital signals.
The TDA18273HN 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.
