APPLICATIONS ISDB-T (one-segment) digital TV for mobile phone Low power portable TV, PDA, PMP, car navigation, and USB applications GENERAL DESCRIPTION The ADMTV201 is a highly integrated, CMOS single-chip, low IF, single-conversion tuner IC for digital mobile TV. It has a single RF input for UHF (470 MHz ~ 806 MHz). It supports one segment of the ISDB-T standard and includes two UHF low noise amplifiers (LNAs), an RF programmable gain amplifier (RF PGA), a downconversion mixer, a complex band-pass filter (CBPF), 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 ADMTV201 consumes ultralow power in comparison to conventional tuners. It is appropriate for portable applications that require low power consumption and includes an industrystandard I2C® serial bus interface. The primary application of the ADMTV201 is the portable terrestrial TV receiver, such as the mobile TV phone. PRODUCT HIGHLIGHTS 1. 2. 3. 4. 5. 6. Ultralow Noise: 2.5 dB Maximum Gain.
