ITD3010: Low-IF Digital TV Tuner IC for Terrestrial DMB & FM

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-Lead 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 I²C serial bus interface. Primary application of the ITD3010 is terrestrial DMB mobile phones and the portable terrestrial DMB receiver.
