The ADMTV202 is a highly integrated, CMOS single-chip, low IF, single-conversion tuner IC for digital mobile TV. It has a single RF input as UHF (470 MHz ~ 806 MHz). It supports one segment of the ISDB-T standard and includes a UHF low noise amplifier (LNA), an RF programmable gain amplifier (RF PGA), a down-conversion mixer, a complex band-pass filter, an IF PGA, a voltage-controlled oscillator (VCO), and a fractional-N phase-locked loop (PLL).

The RF PGA is controlled by an internal RF automatic gain control (RF AGC) loop, and the IF PGA is controlled by a demodulator. The PGAs provide >120 dB of gain control range.

The ADMTV202 consumes ultralow power in comparison to conventional tuners. It is appropriate for portable applications that require low power consumption and includes an industry-standard I2C® serial bus interface. The primary application of the ADMTV202 is the portable terrestrial TV receiver, such as the mobile TV phone.
