Direct-Conversion TV Tuner
General Description
The MAX3580 fully integrated, direct-conversion TV tuner
is designed for Digital Video Broadcasting-Terrestrial
(DVB-T) applications. The integrated tuner covers a
170MHz to 230MHz input frequency range for the VHF-III
band and 470MHz to 878MHz for the UHF band.
The MAX3580 direct-conversion tuner integrates an
RF input switch and a multiband tracking filter, allowing
low-power tuner-on-board applications without the cost
and power-dissipation issues of dual-conversion tuner
solutions. The zero-IF architecture eliminates the need
for SAW filters by providing baseband I and Q outputs
directly to the demodulator. In addition, DC-offset can-
cellation is implemented on-chip using a mixed-signal
architecture to improve the second-order distortion perfor-
mance and the dynamic range of the downstream digitizer
and demodulator.
The MAX3580 features dynamic gain control of more than
76dB and a typical midband noise figure of 4.7dB referred
to the LNA input. The VCO architecture optimizes both in-
band and wideband phase noise for OFDM applications
where sensitivity to both 1kHz phase noise and wideband
phase noise related to strong adjacents can be a problem.
The MAX3580 communicates using a 2-wire serial bus.
The device operates from a typical +3.3V power sup-
ply and dissipates 650mW. The MAX3580 is available
in a small 32-pin TQFN package (5mm x 5mm) with an
exposed paddle.
