TUA6034TCUMA1

Video Processing Overview

The TUA6034TCUMA1 is a 3-band digital TV and set-top-box tuner IC from Infineon Technologies, part of the TAIFUN family. It integrates a mixer-oscillator block with a digitally programmable phase-locked loop (PLL). The device supports PAL, NTSC, DVB-C, DVB-T, ISDB-T, and ATSC standards. It operates within an RF input range of 44.25 MHz to 863.25 MHz across three bands. Key electrical parameters include a nominal noise figure of 8 dB and a maximum input frequency of 863.25 MHz. The PLL utilizes a 4 MHz crystal oscillator and offers reference divider ratios of 24, 28, 32, 64, 80, and 128.

Video Processing Feature Summary

• Integrates a wideband AGC detector with five programmable take-over points and two time constants for internal tuner control.
• Features a high-voltage VCO tuning output and four independent I2C addresses compatible with 3.3V and 5V microcontrollers.
• Includes a symmetrical IF preamplifier capable of driving a compensated SAW filter directly.
• Provides full ESD protection and JEDEC qualification for consumer applications.

Video Processing Applications

• Digital terrestrial TV tuners (DVB-T, ISDB-T)
• ATSC tuner implementations
• Set-top-box applications

Video Processing Procurement Notes

Verify the specific ordering code Q67034-H0009 corresponds to the PG-TSSOP-38 package variant when sourcing. Confirm that the suffix 'T' indicates tape-and-reel packaging if required by assembly equipment. Ensure compatibility with the specified 4 MHz quartz crystal for the internal oscillator circuit. Validate that the application environment meets the thermal requirements defined in the absolute maximum ratings section of the datasheet.

Video Processing Selection Notes

Select this component for designs requiring a single-chip solution for digital TV reception covering multiple broadcast standards. The integrated band switching and low output impedance IF amplifier simplify the external filter design. Consider the availability of the mirrored TUA6036 variant if pinout orientation requires inversion. Ensure the host microcontroller supports the I2C bus protocol up to 400 kHz for proper configuration.

Video Processing Part Context

The TUA6034 belongs to the TAIFUN series of tuner ICs designed for television and video recording applications. It is manufactured by Infineon Technologies and is often paired with the mirrored TUA6036 model. The device represents a consolidated approach to tuner front-end design, combining RF mixing, oscillation, and frequency synthesis into a single integrated circuit.

Video Processing Replacement Considerations

The TUA6036 serves as a mirrored version of the TUA6034. Verify pinout symmetry before substitution. No other direct substitutes are documented in the provided source material.
