Product details
Overview
The MAX3580ETJ+ from Maxim Integrated is a fully integrated, direct-conversion TV tuner IC designed for Digital Video Broadcasting-Terrestrial (DVB-T) reception. It covers VHF-III (170–230MHz) and UHF (470–878MHz) bands, delivers 71dB typical voltage gain, features 4.7dB noise figure at 470MHz, and outputs differential I/Q baseband signals directly to demodulators-enabling SAW-free receiver architectures in digital televisions and set-top boxes.
For engineers reviewing the MAX3580ETJ+ datasheet, MAX3580ETJ+ pinout, MAX3580ETJ+ application, or MAX3580ETJ+ equivalent, this page provides verified functional specifications, validated pin roles, confirmed DVB-T system-level performance metrics (e.g., -85.1dBm sensitivity at 470MHz), and real-world alternative part comparisons grounded in MBRAI/NorDig compliance data.
Technical Context
The MAX3580ETJ+ implements a zero-IF architecture with on-chip DC-offset cancellation using mixed-signal techniques to preserve dynamic range for downstream digitizers. Its Frac-N synthesizer achieves -90dBc/Hz phase noise at 1kHz offset, optimized for OFDM sensitivity to both close-in and wideband phase noise.
It integrates an RF input switch, multiband tracking filter, tunable baseband lowpass filters, and dual AGC loops (RF_AGC and BB_AGC) delivering >76dB total gain control range. Communication occurs via a 2-wire serial interface operating up to 400kHz, with register-controlled VCO autotuning and programmable baseband bandwidth (7MHz/8MHz modes).
Key Specifications

| Frequency Range | VHF-III: 170–230MHz; UHF: 470–878MHz - supports full DVB-T channel coverage across terrestrial broadcast bands. |
| Noise Figure | 4.7dB (typ) at 470MHz - enables high-sensitivity reception in weak-signal environments per NorDig QPSK 1/2 spec (-94.8dBm). |
| Overall Voltage Gain | 71dB (typ) at max gain - sufficient to amplify -93dBm to -20dBm RF inputs to 1VP-P differential baseband output. |
| Power Dissipation | 650mW at +3.3V - optimized for low-power tuner-on-board designs without thermal derating concerns in compact enclosures. |

Key Features
| Feature | Design Value |
|---|---|
| I/Q baseband outputs | Eliminate all IF-SAW filters - reduces BOM cost, board area, and insertion loss in DVB-T front-ends. |
| Frac-N synthesizer | -90dBc/Hz phase noise at 1kHz - ensures robust OFDM symbol recovery under strong adjacent-channel interference. |
| Integrated RF tracking filter | Automatically tunes across VHF/UHF bands - replaces discrete switched-filter banks and simplifies matching network design. |
| Tunable baseband lowpass filters | Programmable 7MHz/8MHz cutoff - matches DVB-T channel bandwidths and suppresses out-of-band noise before ADC sampling. |
| On-chip DC-offset cancellation | Mixed-signal architecture corrects I/Q DC offsets - maintains >60dBc isolation and prevents saturation in downstream demodulators. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar direct-conversion TV tuner applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2160ETJ+ | Single-band (UHF-only: 470–862MHz); no VHF-III support; 5.2dB NF at 600MHz; 550mW power dissipation. | Limited to UHF-only DVB-T deployments; unsuitable for legacy VHF channel reception or hybrid antenna systems. | Select when only UHF coverage is required and lower power consumption is prioritized over full-band flexibility. |
| SI2164-A10-GM | Pin-compatible 32-pin QFN; supports DVB-T/T2/C; higher integration (integrated demodulator); 3.8dB NF at 470MHz; 700mW dissipation. | Enables single-chip DVB-T/T2 solutions but requires different firmware and register mapping; not drop-in compatible with MAX3580ETJ+ layout. | Choose for next-generation T2 support and reduced system complexity, accepting redesign effort for firmware and layout. |
Compared with MAX2160ETJ+, the MAX3580ETJ+ adds VHF-III band support and superior phase noise for OFDM robustness; versus SI2164-A10-GM, it offers proven DVB-T-only stability and simpler register control, though without T2 capability or integrated demodulation.

FAQ
What is the operating temperature range for the MAX3580ETJ+?
The MAX3580ETJ+ is rated for operation from -40°C to +85°C ambient temperature. This industrial-grade range ensures reliable performance in digital televisions, set-top boxes, and portable TV adapters deployed in diverse environmental conditions, including unventilated enclosures and automotive-dock applications.
Does the MAX3580ETJ+ require external SAW filters?
No, the MAX3580ETJ+ does not require external SAW filters. Its zero-IF architecture produces direct differential I/Q baseband outputs, and on-chip DC-offset cancellation preserves dynamic range-eliminating the need for IF-stage filtering and enabling fully integrated, SAW-free DVB-T receiver designs.
How is the MAX3580ETJ+ tuned across VHF and UHF bands?
The MAX3580ETJ+ uses an integrated multiband tracking filter with programmable series/parallel capacitors (controlled via registers 0x04–0x05) and automatic VCO band selection (via register 0x09). VHF-III (170–230MHz) and UHF (470–878MHz) bands are selected by setting TF_BS bit, with corresponding inductor and capacitor values loaded from internal ROM tables.
What is the supply current consumption of the MAX3580ETJ+?
The MAX3580ETJ+ draws 197mA to 225mA typical supply current in active mode at +3.3V, resulting in ~650mW power dissipation. In shutdown mode, current drops below 100µA - enabling low-power standby states in battery-assisted or energy-conscious TV peripheral designs.
Can the MAX3580ETJ+ support both 7MHz and 8MHz DVB-T channel bandwidths?
Yes, the MAX3580ETJ+ supports both 7MHz and 8MHz DVB-T channel bandwidths via programmable baseband filter coefficients. Register 0x0A (BB_BW<3:0>) selects optimal settings, with ROM table entries (address 0x06) providing pre-characterized coefficients for VHF (7MHz) and UHF (8MHz) modes.
