Minimal external components
The ADMTV102 is a highly integrated CMOS single chip zero-
IF conversion tuner IC for mobile-TV standards, such as DVB-
H, T-DMB, DAB and FM. It includes triple RF input bands,
which are VHF/FM, UHF, and L-band. The building blocks of
ADMTV102 are LNAs, RF PGAs, I/Q down-conversion mixers,
bandwidth adjustable low pass filters, baseband variable gain
amplifiers, VCOs and a fractional-N PLL, etc. On-chip low
phase noise VCO along with high resolution fractional-N
frequency synthesizer make in-band phase noise lower than
that of any other conventional tuners.

The ADMTV102 supports multi-band multi-standards with
ultra low power consumption such as 200 mW for DVB-H.
Using small leadless 5 mm × 5 mm 32-LD QFN package, the
ADMTV102 is the best solution for highly integrated multi-
band, multi-standard system and portable application where
low power consumption is critical. It has an industry standard
I2C serial bus interface. Applications of the ADMTV102 are
UHF DVB-H, dual-band T-DMB and FM.
