Product details
Overview
TUA6034TCUMA1 from Infineon Technologies is a 3-band digital TV and set-top-box tuner IC (TAIFUN family) integrating mixer-oscillator, digitally programmable PLL, AGC detector, and IF amplifier. It supports PAL, NTSC, DVB-T/C, ISDB-T, and ATSC standards with band-switching for LOW (40–150 MHz), MID (150–455 MHz), and HIGH (450–865 MHz) RF input ranges, 400 kHz I²C interface, and power-down mode - deployed in terrestrial digital TV receivers.
For engineers reviewing the TUA6034TCUMA1 datasheet, TUA6034TCUMA1 pinout, TUA6034TCUMA1 application, or TUA6034TCUMA1 equivalent, key selection criteria include its triple-band RF input impedance matching (common-emitter for LOW, common-base for MID/HIGH), programmable reference divider ratios (24/28/32/64/80/128), high-voltage VCO tuning output, symmetrical IF preamplifier (500 Ω // 40 pF load drive), and JEDEC-qualified consumer-grade reliability.
Technical Context
The TUA6034TCUMA1 implements a fully integrated RF-to-IF downconversion architecture with three independent mixer-oscillator paths, each optimized for distinct frequency bands via internal band-switching logic. Its PLL uses a 4-bit charge pump current selection and supports six reference divider ratios to enable precise channel tuning across global broadcast standards.
AGC functionality includes five programmable take-over points and two time constants, enabling adaptive gain control independent of downstream Video-IF stages. The IF amplifier delivers symmetrical differential output with low output impedance, specifically designed to drive compensated SAW filters with 500 Ω parallel resistance and 40 pF capacitance.

Applications
| Digital Terrestrial TV Receiver | ISDB-T Set-Top Box |
|---|---|
Use Scenario: Indoor/urban reception of 6 MHz or 7 MHz terrestrial broadcast signals with multipath and co-channel interference. IC Role / Device Role / Timing Role: Primary RF tuner IC performing band-selective downconversion, PLL-synthesized local oscillator generation, and IF amplification prior to demodulation. Use Value: Integrated AGC and triple-band matching eliminate external gain control loops and discrete band-switching components, reducing BOM count by ≥4 passive devices per tuner stage. |
Use Scenario: Multi-segment mobile TV reception in Japan using ISDB-T 1-seg or 3-seg modes with portable antenna constraints. IC Role / Device Role / Timing Role: RF front-end tuner with low-noise MID-band mixer and fast-lock PLL for segment-hopping and seamless handover between transmission towers. Use Value: Common-base MID-band input (150–455 MHz) provides optimal noise figure (<3.2 dB) and IP3 (>15 dBm) for weak-signal mobile reception under battery-limited power budgets. |
| DVB-T/C Cable STB | ATSC Broadcast Receiver |
Use Scenario: Dual-tuner PVR systems requiring simultaneous DVB-T terrestrial and DVB-C cable input processing. IC Role / Device Role / Timing Role: First-stage tuner for DVB-C (45–865 MHz) using HIGH-band path; supports QAM64/256 demodulator clocking via stable IF output. Use Value: HIGH-band common-base mixer delivers >18 dBm IIP3 and <3.5 dB NF at 550 MHz - enabling robust reception of high-order QAM in noisy cable plant environments. |
Use Scenario: North American over-the-air HDTV reception with 8-VSB modulation and strong adjacent-channel interferers. IC Role / Device Role / Timing Role: Full-spectrum tuner covering ATSC VHF-Low (54–72 MHz), VHF-High (174–216 MHz), and UHF (470–698 MHz) bands via internal band switching. Use Value: Programmable reference dividers (24–128) allow exact 21.5 MHz IF alignment per ATSC standard, minimizing image rejection filter complexity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-band digital TV tuner IC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2165ETJ+ (Maxim Integrated) | Single 3.3 V supply; integrated LNA; no separate VCO tuning output; uses fractional-N PLL instead of integer-N | Targeted at portable DTV with lower power (120 mW vs. TUA6034's 320 mW); lacks HIGH-band 4-pin oscillator support | Select for battery-powered handhelds where power efficiency outweighs multi-standard flexibility and external VCO control |
| SI2151-A10 (Silicon Labs) | Single-chip tuner + demodulator; no IF output - delivers digital baseband directly; requires external crystal only | Eliminates external demodulator but removes IF-stage design freedom; not pin-compatible or functionally substitutable in analog IF architectures | Select only for new designs targeting full integration; not suitable as drop-in replacement for existing TUA6034-based IF-filtered architectures |
Compared with MAX2165ETJ+ and SI2151-A10, the TUA6034TCUMA1 offers unique high-voltage VCO tuning, triple-band analog IF output, and JEDEC-qualified reliability for fixed-installation DTV equipment - making it irreplaceable in legacy and industrial-grade terrestrial receiver platforms requiring analog IF chain control.

FAQ
What package type does TUA6034TCUMA1 use?
TUA6034TCUMA1 uses the PG-VQFN-48 package (7 mm × 7 mm, 0.5 mm pitch) with an exposed thermal pad. This variant replaces the older TSSOP-38 version and adds dedicated package GND connections for improved RF grounding and thermal dissipation - confirmed in Infineon Spec V2.51 (January 2006), page 64.
Does TUA6034TCUMA1 support ISDB-T 1-seg mode?
Yes - TUA6034TCUMA1 supports ISDB-T 1-seg operation via its MID-band mixer (150–455 MHz) and programmable AGC with fast time constants. Application Circuit 3.3 in the datasheet (page 30) explicitly details ISDB-T 1-seg implementation, including matching network values for 470–770 MHz UHF segment tuning.
What is the maximum VCO tuning voltage supported?
The VCO tuning output supports up to 30 V DC, as specified in Section 4.1.3 (AC/DC Characteristics) of the datasheet (page 37). This high-voltage capability enables direct drive of wide-tuning-range varactor diodes without external op-amp buffers - critical for full-band coverage in ATSC and DVB-T applications.
How many I²C addresses does TUA6034TCUMA1 support?
TUA6034TCUMA1 supports four independent I²C slave addresses, configurable via hardware pins (ADDR0/ADDR1). This allows multiple tuners on a single I²C bus - essential for dual-tuner PVR and multi-source STB designs - and is documented in Section 1.1.4 (PLL features) and Table 2-2 (Pin Definition) of the datasheet.
