TDA18291HN

Low power DVB / T tuner

Rev. 01 — 28 August 2007

Product short data sheet

1. General description

The TDA18291HN is a BiCMOS integrated circuit receiver intended for digital TV

reception for low power applications (e.g. mobile phone and PDA).

The tuner is designed for the terrestrial digital video broadcast (DVB-T standard) and

handheld DVB standard (DVB-H standard). It operates in the VHFIII and UHF band

(174 MHz to 230 MHz and 470 MHz to 862 MHz) and contains all the functions needed for

a whole receiver chain from (RF) input to baseband IQ outputs: LNA, quadrature mixer,

channel filters and a complete RF PLL with a fully integrated VCO. The PLL can operate

from a number of reference frequencies, fitting almost any mobile platform.

The tuner has been designed for low power mobile applications. Power consumption has

been optimized and a dedicated on-off pin has been added to allow for fast switching, and

thus reduce power, in time-sliced applications. To reduce the footprint of the application,

the number of external components has been minimized and the tuner is available in a

HVQFN32 package (5 mm × 5 mm).
