The ITD3010 is a highly integrated CMOS single chip low-IF
single-conversion tuner IC for terrestrial DMB (Digital
multimedia broadcasting). It supports Korean terrestrial DMB
standard along with analog FM. It includes an LNA, an RF PGA,
an image-rejection down-conversion mixer, 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. The ITD3010 also includes several
regulators, which make it possible to use single 2.85 V power
supply.

The ITD3010 exhibits ultra low power consumption such as 100
mW. Using small leadless 6 mm × 6 mm 40-LD QFN package,
the ITD3010 is the best solution for highly integrated multi­tuner system and portable application where low power
consumption is critical. It has an industry standard I
bus interface. Primary application of the ITD3010 is terrestrial
DMB mobile phones and the portable terrestrial DMB receiver.
