资 源 简 介
The TDA18291HN is a BiCMOS integrated circuit receiver intended for digital TVrecepTIon for low power applicaTIons (e.g. mobile phone and PDA).The tuner is designed for the terrestrial digital video broadcast (DVB-T standard) andhandheld 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 fora 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 operatefrom a number of reference frequencies, fitTIng almost any mobile platform.The tuner has been designed for low power mobile applications. Power consumption hasbeen optimized and a dedicated on-off pin has been added to allow for fast switching, andthus 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 aHVQFN32 package (5 mm ´ 5 mm).
