MAX3580 Direct-Conversion TV Tuner

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 cancellation is implemented on-chip using a Mixed-Signal architecture to improve the second-order distortion performance and the dynamic range of the downstream digitizer and Demodulator
The MAX3580 features dynamic gain 4e2 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 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 -40C to +85C temperature range.
