MAX3580ETJ+T

Video Processing Overview

The MAX3580ETJ+T is a fully integrated direct-conversion TV tuner designed for Digital Video Broadcasting-Terrestrial (DVB-T) applications. It covers the VHF-III band from 170MHz to 230MHz and the UHF band from 470MHz to 878MHz. The device operates on a +3.1V to +3.5V supply, dissipating 650mW with a typical current of 225mA. It features dynamic gain control exceeding 76dB, a typical noise figure of 4.7dB, and a sigma-delta fractional-N synthesizer providing -90dBc/Hz close-in phase noise. Communication is handled via a 2-wire serial bus.

Video Processing Feature Summary

• Zero-IF architecture eliminates SAW filters by providing baseband I and Q outputs directly to the demodulator
• Integrated RF input switch and multiband tracking filter enable low-power tuner-on-board solutions
• On-chip DC-offset cancellation improves second-order distortion performance and dynamic range
• Frac-N synthesizer optimizes in-band and wideband phase noise for OFDM applications

Video Processing Applications

• Digital Televisions
• Digital Terrestrial Set-Tops
• Laptop Televisions
• USB Peripherals

Video Processing Procurement Notes

Verify that the ordering suffix 'T' corresponds to the tape-and-reel package configuration as specified in the manufacturer's documentation. Confirm the component meets lead-free and RoHS compliance requirements indicated by the '+' designation. Ensure the operating temperature range of -40°C to +85°C aligns with the target system environment specifications before finalizing procurement.

Video Processing Selection Notes

Select this component for DVB-T designs requiring a compact solution without external SAW filters. The 32-pin TQFN package measures 5mm x 5mm, suitable for space-constrained layouts. Consider the 650mW power dissipation for thermal management within the host enclosure. Verify compatibility with the required 2-wire serial interface protocol for system integration.
