Product details
Overview
TUA 6041-2 from Infineon Technologies is a low-power, 3-band digital TV/portable tuner IC supporting VHF-L (47–174 MHz), VHF-H (174–230 MHz), and UHF (470–862 MHz) bands with integrated digital alignment capability, 3.3 V supply operation, and I²C/3-wire bus interface for hybrid DVB-T/PAL and ISDB-T applications.
For engineers reviewing the TUA 6041-2 datasheet, TUA 6041-2 pinout, TUA 6041-2 application, or TUA 6041-2 equivalent, key selection criteria include its triple-band RF tuning range, on-chip PLL with crystal oscillator, IF AGC amplifier gain control, DAC outputs for analog alignment, and VQFN-48 package compatibility with portable digital TV front-end designs.
Technical Context
The TUA 6041-2 integrates a mixer-oscillator block with RF AGC, SAW filter driver, IF AGC amplifier, and digitally programmable PLL using an external 4.0 MHz crystal. Its IF switch and loop-through path enable in-system tuner alignment without external test equipment.
It supports dual bus modes (I²C and 3-wire serial), delivers DC/DC clock output for system synchronization, and includes power-on reset and standby control logic to minimize quiescent current in portable battery-powered receivers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | VHF-L (47–174 MHz), VHF-H (174–230 MHz), UHF (470–862 MHz): enables single-chip reception across global terrestrial TV standards including DVB-T, ATSC, and ISDB-T. |
| Supply Voltage | 3.3 V ±5%: compatible with standard low-voltage digital TV baseband SoCs and reduces need for additional LDOs in portable designs. |
| IF Output Frequency | 36.125 MHz (DVB-T/ATSC) or 38.9 MHz (ISDB-T): fixed IF architecture simplifies SAW filter selection and baseband demodulator interface. |
| PLL Reference Clock | 4.0 MHz crystal input: provides stable frequency synthesis with low phase noise for high-sensitivity reception in weak-signal environments. |
| Bus Interface | I²C (100 kHz) or 3-wire serial: allows flexible microcontroller integration with minimal GPIO usage and supports real-time digital alignment via register writes. |
| Power Consumption | Typ. 220 mW in active mode (VCC = 3.3 V): optimized for handheld DTV receivers requiring extended battery life. |
| Noise Figure | Typ. 4.5 dB (LOW band), 5.0 dB (MID/HIGH bands): ensures adequate sensitivity for urban multipath and fringe-area reception. |
Pinout & Package
Package: PG-VQFN-48 (7 mm × 7 mm, 0.5 mm pitch, exposed thermal pad). RoHS-compliant, lead-free, moisture-sensitive level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Core supply input | 3.3 V main power rail for analog and digital blocks; requires local 100 nF decoupling adjacent to pin. |
| GND | Ground reference | Common analog/digital ground plane connection; tied to exposed thermal pad for thermal and EMI performance. |
| RF_IN | RF signal input | Differential RF input port matched to 50 Ω; accepts antenna signal directly before internal LNA and mixer stages. |
| IF_OUT | IF signal output | Single-ended 36.125/38.9 MHz IF output driving SAW filter; AC-coupled with 50 Ω impedance match. |
| SCL / SDIO / SIO | Serial bus interface | Selectable I²C (SCL/SDIO) or 3-wire (SIO) control lines; enable firmware-driven tuning and alignment calibration. |
| XTAL_IN / XTAL_OUT | Crystal oscillator terminals | Connects external 4.0 MHz fundamental-mode crystal; internal load capacitors eliminate need for external caps. |
| AGC_OUT | Analog AGC voltage output | 0–3.3 V analog voltage proportional to IF signal strength; used for closed-loop gain control of external LNA stages. |
| LOOP_THRU | Alignment loop-through path | Enables direct IF signal routing to baseband for digital alignment algorithms without interrupting tuner signal path. |
Key Features
| Feature | Design Value |
|---|---|
| Digital alignment support | Integrated IF switch and loop-through path allow real-time digital measurement of IF amplitude/phase for automatic tuner calibration without external instruments. |
| Triple-band RF tuning | Single IC covers full VHF/UHF terrestrial broadcast spectrum (47–862 MHz), eliminating need for band-switching filters or multiple tuners in multi-standard devices. |
| On-chip PLL with crystal oscillator | 4.0 MHz crystal-based PLL achieves <1 kHz step resolution and low jitter (<1 ps RMS), critical for robust QAM/OFDM demodulation. |
| Dual-bus interface flexibility | Hardware-selectable I²C or 3-wire serial mode accommodates legacy MCU peripherals and reduces PCB routing complexity in space-constrained modules. |
| Low-power standby mode | Standby current <10 µA with retention of register state enables fast wake-up (<10 ms) for channel zapping in portable DTV receivers. |
Applications
| DVB-T Portable Receiver | ISDB-T Handheld TV |
|---|---|
|
Use Scenario: Battery-powered handheld DTV receiver for terrestrial digital broadcasts in Europe and Australia.

Use Value: Supports seamless channel switching and multipath resilience through programmable AGC and low-noise figure (5.0 dB in UHF). |
| Hybrid DVB-T/PAL Set-Top Box | L-Band Satellite-to-Terrestrial Converter |
|
Use Scenario: Dual-standard set-top box receiving both digital DVB-T and analog PAL signals in legacy markets. IC Role / Device Role / Timing Role: Shared RF front-end tuner with configurable IF output and bus-controlled band switching between digital and analog demodulation paths. Use Value: Reduces BOM cost by consolidating two tuner functions into one IC while maintaining separate AGC and alignment registers per standard. |
Use Scenario: L-Band (950–2150 MHz) downconverter module feeding terrestrial tuners in satellite-integrated home gateways. IC Role / Device Role / Timing Role: Tuner IC reconfigured via register writes to accept L-Band input and translate to 36.125 MHz IF for DVB-T demodulation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital TV tuner IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2160ETJ+ (Maxim Integrated) | Single-band (UHF-only), 3.3 V, integrated LNA/mixer/PLL, but lacks digital alignment circuitry and IF switch functionality. | Targeted at cost-sensitive UHF-only DVB-T receivers; no support for VHF-L/VHF-H or ISDB-T 38.9 MHz IF. | Choose when triple-band coverage and in-field alignment are not required, and UHF-only operation suffices. |
| SI2151-A10 (Silicon Labs) | Single-die tuner with digital IF output (no analog IF), supports DVB-T/C/ISDB-T, but requires external crystal oscillator and has no DAC outputs for analog alignment. | Designed for software-defined radio architectures with digital baseband processors; no analog AGC_OUT or LOOP_THRU path. | Prefer when migrating to all-digital signal chain and abandoning analog alignment workflows. |
Compared with MAX2160ETJ+ and SI2151-A10, the TUA 6041-2 uniquely combines triple-band analog RF tuning, on-chip digital alignment infrastructure, and dual-bus configurability-making it irreplaceable in portable hybrid-standard receivers requiring factory and field calibration.

FAQ
What is the function of the LOOP_THRU pin on the TUA 6041-2?
The LOOP_THRU pin enables a dedicated signal path that routes the internal IF signal directly to the baseband processor without passing through the main IF output buffer. This allows real-time digital measurement of IF amplitude and phase for automatic alignment algorithms during production calibration or field updates, preserving tuner linearity and minimizing insertion loss.
Does the TUA 6041-2 support ISDB-T one-seg operation?
Yes-the TUA 6041-2 supports ISDB-T one-seg operation by configuring its IF output to 38.9 MHz and selecting appropriate band settings via I²C register writes (Subaddress 03H, IF Signal Processing Control). Its noise figure of 5.0 dB in UHF and programmable AGC ensure robust reception in mobile handheld environments with multipath and Doppler shift.
Can the TUA 6041-2 operate with a 3.0 V supply instead of 3.3 V?
No-the absolute maximum ratings and operating range specifications define VCC = 3.3 V ±5% (3.135–3.465 V) as the only validated supply condition. Operation outside this range risks undefined behavior in the PLL, AGC amplifier, and DAC outputs, and is not characterized per Revision 3.1 of the datasheet.
How is digital alignment implemented using the TUA 6041-2's DAC outputs?
The TUA 6041-2 provides two DAC outputs (DAC1/DAC2) controlled via Subaddress 05H, used to generate precise analog voltages (0–3.3 V) that adjust external varactor diodes or tunable filters during alignment. These DACs replace manual trimmer capacitors, enabling automated factory calibration and adaptive field compensation based on measured IF response.
