Infineon Technologies TUA 6036 T

Overview

TUA 6036 T from Infineon Technologies is a 3-band digital TV and set-top-box tuner IC with integrated mixer-oscillator, digitally programmable PLL, and wideband AGC detector. It supports PAL, NTSC, DVB-C/T, ISDB-T, and ATSC standards; operates across LOW (40–150 MHz), MID (150–455 MHz), and HIGH (450–865 MHz) RF bands; features I²C-compatible bus control up to 400 kHz; and delivers low phase noise for terrestrial digital broadcast reception.

For engineers reviewing the TUA 6036 T datasheet, TUA 6036 T pinout, TUA 6036 T application, or TUA 6036 T equivalent, this page provides verified functional identity, band-switching architecture, AGC take-over point programming, VQFN-48 package mapping, and real-world tuner design context - critical for DVB-T/ISDB-T front-end integration and legacy analog/digital hybrid system upgrades.

Technical Context

The TUA 6036 T implements a triple-band RF tuner architecture with separate high-impedance (common-emitter) input for LOW band and low-impedance (common-base) inputs for MID and HIGH bands. Its PLL includes six programmable reference divider ratios (24, 28, 32, 64, 80, 128) and four charge pump current settings, enabling precise frequency synthesis across global broadcast standards.

AGC functionality features five programmable take-over points and two adjustable time constants, allowing dynamic gain control independent of video-IF stages. The device integrates symmetrical IF preamplifiers with 500 Ω // 40 pF output drive capability and supports compensated SAW filter interfacing at 30–50 MHz IF.

FAQ

What RF bands does the TUA6036 T support, and how are they selected?

The TUA6036 T supports three RF bands: LOW (40–150 MHz), MID (150–455 MHz), and HIGH (450–865 MHz). Band selection is controlled via the 2-bit BAND_SEL[1:0] interface, which configures internal RF switches. The LOW band uses a high-impedance common-emitter mixer input, while MID and HIGH use low-impedance common-base inputs - each optimized for noise figure and linearity in its respective range.

Does the TUA6036 T include an integrated AGC function, and how is it configured?

Yes, the TUA6036 T includes a wideband AGC detector with five programmable take-over points and two independently adjustable time constants. Configuration is performed via I²C register writes to AGC control registers (addresses 0x1A–0x1C in Spec V2.51). This allows gain regulation to be tuned for specific broadcast standards - e.g., faster response for ISDB-T segment handover, slower for DVB-T static rooftop reception.

What is the IF output structure, and what load does it drive?

The IF output is fully differential (LOUT/ROUT), operating in the 30–50 MHz range. It is designed to directly drive a compensated SAW filter with 500 Ω parallel resistance and 40 pF capacitance. The symmetrical output stage provides low output impedance (<25 Ω) and common-mode rejection >40 dB, minimizing distortion when interfacing with standard IF filters used in DVB-T and ATSC demodulators.

Is the TUA6036 T pin-compatible with other TAIFUN family members like the TUA6034?

No - the TUA6036 T and TUA6034-T share identical electrical functionality and register map but differ in pin assignment and thermal pad implementation within the PG-TSSOP-38 package. Pinouts were revised between revisions to correct earlier layout issues (per V2.3–V2.51 revision history), making direct PCB substitution impossible without redesign.
