Infineon Technologies TUA 6039

Overview

TUA 6039 from Infineon Technologies is a 3-band digital/hybrid tuner IC with integrated IF AGC amplifier, supporting ATSC, DVB-T, ISDB-T, and analog PAL/SECAM broadcast standards. It operates across LOW (30–200 MHz), MID (130–500 MHz), and HIGH (400–1000 MHz) RF bands, delivers 45 MHz IF output, and features I²C interface control with on-chip PLL and ADC for signal level monitoring.

For engineers reviewing the TUA 6039 datasheet, TUA 6039 pinout, TUA 6039 application, or TUA 6039 equivalent, this device is selected for multi-standard terrestrial TV tuners requiring band-switching agility, low-noise RF front-end integration, and precise IF gain control in compact consumer and set-top box designs.

Technical Context

The TUA 6039 integrates three independent mixer-oscillator paths with band-selectable SAW filter drivers and a dedicated IF AGC amplifier stage. Its PLL supports programmable reference dividers (R=1 to 255) and charge pump currents (100 µA to 800 µA), enabling fine frequency resolution across all bands.

The IC includes an on-chip 10-bit ADC for RSSI monitoring and supports loop-thru functionality for cascaded tuner architectures. RF AGC take-over point is configurable at −20 dBm to −5 dBm, and IF output is DC-coupled with 45 MHz center frequency and ±1.5 MHz bandwidth.

FAQ

Does the TUA 6039 support DMB-TH standard?

Yes, Revision 2.6 of the datasheet explicitly adds DMB-TH standard support in the functional description and application circuits. The IC's triple-band architecture and programmable IF filtering allow configuration for DMB-TH's 8 MHz channel bandwidth and QPSK/16-QAM modulation schemes within the 470–862 MHz UHF band.

What is the thermal pad connection requirement for the VQFN-48 package?

The exposed thermal pad on the PG-VQFN-48 package must be soldered to a solid copper thermal land on the PCB, connected to GND via ≥4 thermal vias (0.3 mm diameter) to inner ground planes. This ensures junction temperature remains ≤115°C at 3.3 V/120 mA typical operating conditions.

Can the TUA 6039 operate without an external crystal?

No. The IC requires a 24.576 MHz fundamental-mode crystal connected between OSCLOWIN and OSCLOWOUT pins. Internal oscillator circuitry uses this reference for PLL synthesis; no internal RC oscillator or clock input bypass mode is supported per Section 3.4.2 of the datasheet.

Is the IF output AC- or DC-coupled?

The IF output (IF_OUTP/IF_OUTN) is DC-coupled, as confirmed by the "DC Coupled IF Output" label in Figure 5 (Functional Block Diagram) and the absence of coupling capacitors in all application circuits (Figures 9–12). This allows direct interface to DC-coupled demodulators without external biasing networks.
