Infineon Technologies TUA 6030

Overview

TUA6030 from Infineon Technologies is a 3-band analog/digital TV tuner IC integrating mixer-oscillator blocks and a digitally programmable PLL for PAL/NTSC and DVB reception. It supports LOW (40–140 MHz), MID (150–455 MHz), and HIGH (450–865 MHz) bands, features 75 Ω symmetrical IF output impedance, I²C-compatible control up to 400 kHz, and operates with a 4 MHz crystal reference. Used in analog TV sets, VCRs, and set-top receivers.

For engineers reviewing the TUA6030 datasheet, TUA6030 pinout, TUA6030 application, or TUA6030 equivalent, key selection considerations include band-switching architecture, AGC take-over point programmability (5 settings), phase noise performance (≥92 dBc/Hz @ ±10 kHz in LOW/MID bands), and P-TSSOP-38 package compatibility with legacy tuner PCB layouts.

Technical Context

The TUA6030 implements a triple-band tuner architecture with three distinct mixer configurations: high-impedance common-emitter input for LOW band, and low-impedance common-base inputs for MID and HIGH bands. Its oscillator section uses two 2-pin asymmetrical LC oscillators (LOW/MID) and one 4-pin symmetrical oscillator (HIGH), enabling band-specific impedance matching and noise optimization.

The integrated PLL supports four programmable reference divider ratios (24, 64, 80, 128) and charge pump current tuning, delivering frequency resolution of 31.25–166.7 kHz across 40–1024 MHz. Lock detection is provided via an I²C-readable flag, and AGC includes two programmable time constants and five selectable take-over points independent of video-IF AGC.

Key Specifications

Pinout & Package

Packaged in P-TSSOP-38 (3.6 mm × 12.5 mm, 0.65 mm pitch), the TUA6030 integrates 8 I/O ports (P0–P7), including 4 PNP, 3 NPN, and 1 dual-function NPN/ADC port (P6), plus dedicated I²C (SCL/SDA), lock flag (LOCK), and band-select control pins.

FAQ

What is the maximum operating junction temperature for the TUA6030?

The TUA6030 has a maximum junction temperature of +125 °C, as specified in its absolute maximum ratings. This rating assumes proper PCB thermal design with adequate copper pour and via stitching beneath the exposed pad of the P-TSSOP-38 package. Operation above this limit risks parametric shift and accelerated aging of internal bipolar transistors.

Does the TUA6030 support automatic band switching based on input frequency?

No - band selection is controlled explicitly via three dedicated digital inputs (RF_LO, RF_MI, RF_HI). The IC does not perform autonomous frequency detection or auto-switching; external microcontroller firmware must determine the correct band and assert the corresponding control lines before tuning.

Can the P6 pin be used simultaneously as an ADC input and NPN output?

No - P6 is a dual-function pin but operates in only one mode at a time. Configuration is determined by the Auxiliary Byte bit 5 setting at power-on reset (default = 1, enabling ADC mode). To use it as an NPN output, bit 5 must be cleared via I²C write prior to activation.

Is the TUA6030 pin-compatible with the TUA6032 variant?

Yes - both TUA6030 and TUA6032 share identical P-TSSOP-38 packaging, pinout, and electrical specifications. The TUA6032 is a mirror-imaged version intended for alternate PCB layout routing; functional behavior, register map, and timing are fully identical.
