Specifications of MAX2165ETI+

Lead Free Status / RoHS Status
Lead free / RoHS Compliant
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 I
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.
