Single-Conversion DVB-H Tuner

General Description

The MAX2165 direct-conversion tuner IC is designed for

handheld digital video broadcast (DVB-H) applications.

The tuner covers a 470MHz to 780MHz input frequency

range and features an I/Q baseband interface.

The MAX2165’s direct-conversion architecture elimi-

nates the need for an IF-SAW filter, allowing for

reduced bill of materials cost. The design integrates a

variable-gain, low-noise amplifier (LNA); a notch filter;

an RF tracking filter; a quadrature mixer; a power

detector; programmable baseband lowpass channel-

selection filters; baseband variable-gain amplifiers

(VGA); DC offset correction circuitry; and a complete

fractional-N frequency synthesizer. The part is program-

mable through a 2-wire I2C-compatible serial interface.

The MAX2165 integrates a tuneable notch filter. This fil-

ter is designed to notch out interfering signals in the

830MHz to 950MHz frequency range to allow for opera-

tion in the presence of large cellular signals.

Programmable baseband channel-selection filters allow

for operation with 7MHz and 8MHz channels. Digital DC

offset correction circuitry supports time-sliced operation

by minimizing power-up time delay. The fractional-N

synthesizer reduces VCO lock time and minimizes

close-in phase noise, eliminating the need for power-

hungry, phase-noise reduction algorithms.

The MAX2165 is available in a tiny, 5mm x 5mm x

0.8mm, 28-pin thin QFN package with an exposed pad-

dle. It is specified for operation over the -40°C to +85°C

extended temperature range.
