2. TUNER
FT 2112/3/8/9 are newly developed Half-NIM modules designed for both digital
(DVB-T / T2 and DTMB for terrestrial China) and analog TV reception in compliance with
the European ATV standards for analogue, as well as with the terrestrial standard ETS 300
744 for DVB-T and the new terrestrial standard ETS 302 755 for DVB-T2. 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 & gain-controllable IF that offers a
sufficient output level to be connected directly to an A/D converter.
In active antenna option, the following circuit are used. ANT_CTRL pin is controlled by
microcontroller. If ANT_CTRL is low, ANT_PWR will be low. If ANT_CTRL is high,
ANT_PWR will be high. OVER_CUR_DETECT pin is a monitor for short circuit in antenna.
OVER_CUR_DETECT is low, ANT_CTRL will be low, so ANT_PWR will be low. Finally,
short circuit protection is done by circuits and microcontroller.
