MTV301
Low IF Tuner IC for T-DMB/DAB/FM
The MTV301 is a highly integrated CMOS, single-chip tuner IC for mobile application like terrestrial digital multimedia broadcasting (DMB), dual-band digital audio broadcasting (DAB), and FM. It includes three LNAs, a RF Attenuator, a down conversion mixer, a bandwidth-adjustable filter, a programmable gain amplifier, a VCO, and a fractional-N PLL. On-chip low phase noise VCO along with high-resolution fractional-N frequency synthesizer makes in-band phase noise lower than that of any other conventional tuner. The MTV301 uses dual power 1.8V and I/O and include main LDO, so can support single power mode supply. It has an industry-standard I2C serial bus interface.
The MTV301 exhibits very low power consumption, such as 55 mW. With a small 4 mm × 4 mm 24-lead LFCSP (QFN) package, the MTV301 is the best solution for highly integrated multi tuner system applications and portable applications, where low power consumption is required critically.
