TDA18214

TDA18214 Silicon tuner for digital terrestrial and cable TV reception Rev. 1 — 13 July 2012 Preliminary short data sheet 1. General description The TDA18214AHN and TDA18214HN are high performance silicon tuners designed for digital terrestrial and digital cable TV reception. The TDA18214AHN and TDA18214HN support all digital TV standards and deliver a Low IF (LIF) signal to a demodulator. The TDA18214AHN and TDA18214HN facilitate STB design by: Allowing on-board integration Drastically reducing the tuner Bill Of Material (BOM) Providing flexibility in system solution development Allowing straightforward, cost effective dual and multi-tuner applications optimization In multi-tuner application, the TDA18214AHN is the master tuner whereas the TDA18214HN is a slave tuner. 2.
