APPLICATIONS
ISDB-T (one-segment) digital TV for mobile phone
Low power portable TV, PDA, PMP, car navigation, and USB
applications
GENERAL DESCRIPTION
www.DaTthaeSAheDeMt4UT.Vco2m01 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 ampli-
fiers (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 industry-
standard I2C® serial bus interface. The primary application of
the ADMTV201 is the portable terrestrial TV receiver, such
as the mobile TV phone.
