GENERAL DESCRIPTION

The ADMTV102 is a highly integrated CMOS, single-chip,

zero-IF conversion tuner IC for mobile TV standards, such as

DVB-H, DVB-T, DTMB, and CMMB. The part includes an RF

input band, UHF. The building blocks of the ADMTV102 include

LNAs, RF PGAs, I/Q downconversion mixers, bandwidth-

adjustable low-pass filters, baseband VGAs, a VCO, and a

fractional-N PLL. The on-chip low phase noise VCO, along

with the high resolution fractional-N frequency synthesizer, makes

in-band phase noise low enough for mobile TV applications.

The ADMTV102 supports dual-band mobile TV standards with

low power consumption, such as 200 mW for DVB-H. Using a

small, Pb-free, 5 mm × 5 mm 32-lead LFCSP, the ADMTV102

is an ideal solution for highly integrated dual-band mobile and

portable applications where low power consumption is critical.

ADMTV102 include DVB-H, DVB-T, DTMB, and CMMB.
