Product details
Overview
MAX3580ETJ+T 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, achieves 4.7dB noise figure at 470MHz, and operates from +3.1V to +3.5V with 650mW power dissipation in digital television front-end signal chains.
For engineers reviewing the MAX3580ETJ+T datasheet, MAX3580ETJ+T pinout, MAX3580ETJ+T application, or MAX3580ETJ+T equivalent, this page provides verified RF tuning performance, zero-IF I/Q baseband output specifications, AGC control behavior, phase-noise compliance for OFDM, and package-level thermal and layout guidance for DVB-T set-top and embedded TV designs.
Technical Context
The MAX3580ETJ+T implements a fractional-N synthesizer with 20-bit resolution and Frac-N architecture optimized for -90dBc/Hz close-in phase noise at 1kHz offset-critical for OFDM sensitivity in presence of strong adjacent channels. Its zero-IF architecture eliminates external SAW filters by delivering differential I/Q baseband outputs directly to the demodulator.
On-chip DC-offset cancellation uses mixed-signal feedback to suppress second-order distortion, improving dynamic range for downstream digitizers. The integrated multiband tracking filter and tunable baseband lowpass filters support full-band VHF-III and UHF operation without external band-switching components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Input 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 for weak-signal reception in urban multipath environments |
| Overall Voltage Gain | 71dB (typ) at max gain - sufficient to amplify -93dBm to -20dBm RF inputs to 1VP-P baseband output |
| Phase Noise | -90dBc/Hz at 1kHz offset - meets MBRAI/NorDig requirements for OFDM symbol timing stability |
| Power Dissipation | 650mW at VCC = +3.3V - requires thermal-aware PCB layout with exposed paddle soldered to ground plane |
| Supply Voltage | +3.1V to +3.5V - compatible with standard 3.3V LDOs; tolerates ±5% variation without performance degradation |
| AGC Range | 76dB dynamic gain control - maintains constant baseband output level across >100dB RF input variation |
Pinout & Package
MAX3580ETJ+T is housed in a 32-pin TQFN package (5mm × 5mm) with exposed thermal pad (EP), rated for -40°C to +85°C operation. The exposed paddle must be soldered to the PCB ground plane for optimal RF performance and thermal management.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2 | SDA, SCL | 2-wire serial interface lines - require external pull-up resistors to VCC_SYN; support 400kHz clock rate |
| 4, 3 | RFIN, RFIN2 | Dual RF inputs - RFIN selected via RFS bit in Register 0x05; supports antenna diversity or dual-tuner configurations |
| 9, 19 | RF_AGC, BB_AGC | Analog gain control inputs - 0.5V to 2.85V range sets 76dB RF and 50dB baseband VGA gain respectively |
| 15–18 | BBQ-, BBQ+, BBI-, BBI+ | Differential I/Q baseband outputs - 1VP-P nominal, 60Ω differential impedance, DC-coupled with programmable highpass cutoff (20–200Hz) |
| 20, 21 | VCC_VCO, VTUNE | VCO supply and tuning voltage - VTUNE connects directly to PLL loop filter; VCC_VCO requires local 100pF decoupling |
| 24, 25 | CP, GND_CP | Charge-pump output and ground - CP drives loop filter; GND_CP must be isolated from digital ground to minimize reference spurs |
| 32, EP | XE, Exposed Pad | Crystal oscillator feedback and thermal ground - XE connects to capacitive divider in self-oscillating mode; EP must be soldered to PCB ground |
Key Features
| Feature | Design Value |
|---|---|
| I/Q Baseband Outputs | Eliminate all IF-SAW filters - reduces BOM cost and board area while enabling direct connection to DVB-T demodulators |
| Frac-N Synthesizer | -90dBc/Hz phase noise at 1kHz offset - ensures robust OFDM symbol recovery under strong adjacent-channel interference |
| Integrated Tracking Filters | Automatically tune across VHF/UHF bands - removes need for external band-switched LC networks or relays |
| Tunable Baseband LPF | Programmable 7MHz/8MHz passband - matches DVB-T channel bandwidths without external component changes |
| DC-Offset Cancellation | Mixed-signal on-chip correction - improves second-order IMD performance and prevents ADC saturation in zero-IF architecture |
| Ultra-Small TQFN | 5mm × 5mm footprint with exposed pad - enables compact tuner modules for USB peripherals and laptop TVs |

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 |
|---|---|---|---|
| SI2151-A10-GM | Single-ended baseband outputs; 3.3V-only supply; no integrated tracking filter - requires external band-switching | Targeted at cost-sensitive USB dongles with simpler RF front-end; lacks VHF-III support below 230MHz | Select when board space allows external filters and VHF-III coverage is not required; lower integration but mature driver support |
| MT2063DN | Higher power (850mW); supports ATSC/DVB-C in addition to DVB-T; larger 40-pin QFN package | Suitable for multi-standard broadcast receivers; includes built-in analog video DAC not present in MAX3580ETJ+T | Choose for hybrid DVB-T/ATSC platforms where additional standards support justifies higher power and footprint |
Compared with SI2151-A10-GM and MT2063DN, the MAX3580ETJ+T offers superior VHF-III coverage, lower power, and tighter phase-noise performance specifically optimized for DVB-T OFDM, making it ideal for space-constrained, high-sensitivity terrestrial TV applications.

FAQ
What is the operating temperature range for the MAX3580ETJ+T?
The MAX3580ETJ+T is specified for operation from -40°C to +85°C ambient temperature. This industrial-grade range ensures reliable performance in digital television chassis, set-top enclosures, and laptop thermal environments. Junction temperature must not exceed +150°C, and the exposed paddle must be thermally coupled to the PCB ground plane to maintain safe thermal resistance.
Does the MAX3580ETJ+T support both VHF-III and UHF DVB-T bands?
Yes, the MAX3580ETJ+T fully supports both VHF-III (170–230MHz) and UHF (470–878MHz) bands required for DVB-T reception. Band selection is controlled via the TF_BS bit in Register 0x05, and the integrated multiband tracking filter automatically adapts component values using on-chip ROM tables for optimal matching across the entire range.
How does the MAX3580ETJ+T handle DC offset in its zero-IF architecture?
The MAX3580ETJ+T implements on-chip mixed-signal DC-offset cancellation using dedicated DACs and feedback loops per I/Q channel. Registers 0x0B–0x0C configure correction thresholds, speed, and DAC values. This architecture actively suppresses LO leakage-induced DC offsets, preventing ADC saturation and preserving dynamic range without requiring external AC-coupling capacitors.
What package type and thermal considerations apply to the MAX3580ETJ+T?
The MAX3580ETJ+T uses a 32-pin TQFN package (5mm × 5mm) with an exposed thermal pad (EP). For optimal RF performance and thermal management, the EP must be soldered to a solid copper ground plane with ≥4 thermal vias. The device dissipates 650mW at +3.3V, and derating begins above +70°C ambient (21.3mW/°C).
Can the MAX3580ETJ+T be used with standard 27MHz crystal references?
Yes, the MAX3580ETJ+T accepts reference frequencies from 4MHz to 27MHz via the XB/XE pins. A 27MHz crystal is fully supported and commonly used to achieve optimal phase-noise performance in the UHF band. The internal REF_BUFF provides a buffered 0.7VP-P output, and register settings (e.g., RDIV in Register 0x06) allow scaling for different reference frequencies.
