ADMTV300 is a single chip synthesized tuner for T-DMB, dual-band DAB and FM receiver, which adopts a low-IF single-conversion architecture that eliminates all SAW filters.
The ADMTV300 is a highly integrated CMOS low‑IF single‑conversion tuner IC designed for mobile applications such as terrestrial DMB, dual‑band DAB and FM. It integrates LNAs, RF PGA, mixer, adjustable band‑pass filter, IF programmable gain amplifier, VCO and fractional‑N PLL in a 5 mm × 5 mm 32‑LFCSP package.
Key features include ultra‑low power consumption (77 mW in Band‑III, 84 mW in L‑Band), a single 1.2 V supply, PC serial bus interface, and minimal external components, making it suitable for portable TV, PDA, car A/V and FM radio applications.
