This is a low power mobile TV tuner IC for ISDB-T digital TV receiver. It features a single chip synthesized tuner with low IF single conversion architecture, eliminating all SAW filters.
The ITD2010 is a highly integrated CMOS single‑chip tuner for terrestrial digital TV. It features a low‑IF single‑conversion architecture, eliminating the need for SAW filters, and offers ultra low power consumption of only 100 mW. The device includes on‑chip fractional‑N PLL, low‑phase‑noise VCO, adjustable low‑pass filter, and an IF variable‑gain amplifier for direct connection to digital demodulators.
The tuner supports VHF (90 ~ 222 MHz) and UHF (470 ~ 770 MHz) dual RF inputs and complies with ISDB‑T 1‑segment and 3‑segment standards. It is supplied in a small 40‑lead QFN (6 × 6 mm) package and uses a standard 12‑C serial bus interface, making it suitable for portable TV, PDA, and mobile phone applications.
