GENERAL DESCRIPTION

The ITD2010 is a highly integrated CMOS single chip low-IF
single-conversion tuner IC for digital TV. It has dual RF inputs
as VHF (90 ~ 222 MHz) and UHF (470 ~ 770 MHz). It supports
1-segment and 3-segment of ISDB-T standard. It includes
VHF/UHF LNAs, VHF/UHF PGAs, VHF/UHF image-rejection
down-conversion mixers, a bandwidth adjustable low pass filter,
an IF variable gain amplifier, a VCO 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.

PRODUCT HIGHLIGHTS

1. Single chip synthesized tuner for terrestrial digital TV
receiver

2. Low-IF single-conversion architecture which eliminates all
SAW filters

3. Low power consumption: 100 mW

The ITD2010 exhibits ultra low power consumption, while
conventional tuners consume over 1 watt. Using small 40-lead
QFN [LFCSP_UQ] package, the ITD2010 is the best solution
for highly integrated multi-tuner system and portable
application where low power consumption is required. It has an
industry standard I
of the ITD2010 is the portable analog/digital terrestrial TV
