Direct-Conversion TV Tuner  
MAX3580  
General Description  
Features  
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.  
o 650mW Power Dissipation (at V  
= +3.3V)  
CC  
o I and Q Baseband Outputs Eliminate All IF-SAW  
Filters  
o Integrated RF Tracking Filters  
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.  
o Tunable Baseband Lowpass Filters  
o Full-Band VHF-III and UHF Tuning  
o +38dB Digital ACPR, +47dB Analog ACPR  
o Low Noise Figure: 4.7dB (typ)  
o Frac-N Synthesizer for -90dBc/Hz Close-In  
Phase Noise  
o Baseband Overload Detector Controls RF AGC if  
Desired  
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.  
o +3.1V to +3.5V Supply Voltage Range  
o Ultra-Small, 5mm x 5mm Thin QFN Package  
Pin Configuration/  
Functional Diagram  
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. Electrical performance is guaranteed  
over the extended -40°C to +85°C temperature range.
