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 per-
formance 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 opti-
mizes 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 supply
and dissipates 650mW. The MAX3580 is available in a
small 32-pin thin QFN package (5mm x 5mm) with an
exposed paddle.
