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, bandwidth­adjustable 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.

For more information on the ADMTV102, email Analog Devices, Inc., at [e-mail].

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.
The part has an I

C® serial bus interface. Applications for the

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