19-0611; Rev 4; 3/08 EVALUATION KIT AVAILABLE Direct-Conversion TV Tuner MAX3580 General Description Features The MAX3580 fully integrated, direct-conversion TV tuner 650mW Power Dissipation (at VCC = +3.3V) is designed for Digital Video Broadcasting-Terrestrial(DVB-T) applications. The integrated tuner covers a I and Q Baseband Outputs Eliminate All IF-SAW 170MHz to 230MHz input frequency range for the VHF-III Filters band and 470MHz to 878MHz for the UHF band. Integrated RF Tracking Filters The MAX3580 direct-conversion tuner integrates an RFinput switch and a multiband tracking filter, allowing Tunable Baseband Lowpass Filters low-power tuner-on-board applications without the cost Full-Band VHF-III and UHF Tuning and power-dissipation issues of dual-conversion tunersolutions. The zero-IF architecture eliminates the need +38dB Digital ACPR, +47dB Analog ACPR for SAW filters by providing baseband I and Q outputs Low Noise Figure: 4.7dB (typ) directly to the demodulator. In addition, DC-offset can-cellation is implemented on-chip using a mixed-signal Frac-N Synthesizer for -90dBc/Hz Close-In architecture to improve the second-order distortion per- Phase Noise formance and the dynamic range of the downstreamdigitizer and demodulator. +3.1V to +3.5V Supply Voltage Range The MAX3580 features dynamic gain control of more Ultra-Small, 5mm x 5mm Thin QFN Package than 76dB and a typical midband noise figure of 4.7dBreferred to the LNA input. The VCO architecture opti-mizes both in-band and wideband phase noise forOFDM applications where sensitivity to both 1kHzphase noise and wideband phase noise related tostrong adjacents can be a problem. Pin Configuration/ The MAX3580 communicates using a 2-wire serial bus.The device operates from a typical +3.3V power supply Functional Diagram and dissipates 650mW. The MAX3580 is available in asmall 32-pin thin QFN package (5mm x 5mm) with anexposed paddle. Electrical performance is guaranteed TOP VIEW AL FFU LL P XT P SYN C over the extended -40°C to +85°C temperature range. B _ X _ C C EF_ ND_ ND_
