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).
