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.
