FT21XX

FT 21XX are newly developed low-cost Half-NIM modules designed for both digital (DVB-T/C) and analog
TV reception in compliance with the European ATV standards for analogue, as well as with the terrestrial
standard ETS 300 744 and cable standard ETS 300429 for digital. It consists of a 3-band RF tuner, which
receives RF signal and down-converts it to an IF frequency of 36MHz for digital and 38.9MHz for analog
IF. The analogue IF output can directly drive a SAW filter. A digital IF Stage, which consists of one SAW
filter & gaincontrollable IF that offers a sufficient output level to be connected directly to an A/D converter.
