Applications

The ADMTV202 is a highly integrated CMOS single chip low­IF single-conversion tuner IC for digital mobile TV. It has dual
RF inputs as UHF (470 ~ 806 MHz) and VHF (90 ~ 222 MHz).
It supports 1-segment and 3-segment of ISDB-T standard. It
includes UHF/VHF LNAs, a RF PGA, a down-conversion mixer,
a complex band pass filter, an IF PGA, a VCO and a fractional­N PLL, etc.

The RF PGA is controlled by an internal RF AGC loop and IF
PGA is controlled by a demodulator. The ADMTV202’s PGAs
provide in excess of 120 dB of gain control range.
