The ADMTV300 is a highly integrated CMOS, single-chip, low IF single-conversion 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 PGA, a downconversion mixer, a bandwidth-adjustable image rejection band-pass filter, an IF 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 ADMTV300 uses single 1.2 V power supply. It has an industry-standard I2C serial bus interface.
The ADMTV300 exhibits very low power consumption, such as 70 mW. With a small 5 mm × 5 mm 32-lead LFCSP (QFN) package, the ADMTV300 is the best solution for highly integrated multituner system applications and portable applications, where low power consumption is critical.
Product Highlights
- Single chip synthesized tuner for terrestrial DMB, dual-band DAB and FM receiver
