STN-25T2000

 

OVERVIEW stn-25t1000

The STN25T2000 is the latest state of the art low_IF tuner from SiTune Corporation. It has the best of the two worlds: it is LOW_IF and therefore does not have the ZERO_IF issues specifically for non_OFDM standards like ATSC and Analog TV and it is LOW_POWER as opposed to other silicon tuners with 40MHz IF frequencies of course CAN tuners. STN25T2000 has taken care of the Image reject issue (intrinsic to LOW_IF structure) with a novel patented technique. It covers the whole band from 50MHz to 900MHz with one RF input. Although differential RF input is preferred, it works with single_ended input directly from Antenna as well. It features a very sophisticated internal RF AGC to take care of large signal situations.
